My latest WIP is basically a futuristic/ fantasy hydro power device. What's going on isn't as important as how it looks (I don't have a clue what it is really). All thoughts are welcome. Originally thought of as a game art concept that I may completely model out. I started with a rough 3d render and then took it into photoshop. Thanks

This is a minor update with some perspective issues fixed on the little tank guy and a few other things. What (if anything) should I work on before I consider this enough and move on? Thanks

Whether this is finished depends on if you want it to be merely functional as reference for someone else to build it (for a game, for example), or if it needs to stand on its own as a piece of artwork. If it's the latter, you'll need to give it a bit more TLC--especially stuff in the background like the mountains. The clouds also look a bit raw. You might also want to populate the foreground with people so there's a sense of scale.

I added a little bit to the front mountains and smudged the clouds. Unsharp mask applied as well. Thanks!

Here it is. Thanks!

Your figure currently lines up with that lighter valued vertical shape right above it. That kind of unintentional matching is never good for composition. Similarly, that little vehicle on the left is almost lined up with the vertical structure behind it.

You also need to make sure that when you depict man-made artificial objects of perfect geometric shapes, that they are in fact, precisely painted. Your hydro device isn't as symmetrical as could be (for example, if you make a copy of half of it vertically and flip it horizontally to a mirror position, and then change the opacity, you'll that it's kind of crooked in some places that really should be perfectly symmetrical. If this was a very rough speed-paint sketch, then no one would care, but you've portrayed it as a finished and detailed painting, so people will have that expectation.

You might also want to consider the fact that in some areas, you have the sky dome bouncing its blue onto shadow areas, but it's not consistent. You need to be more consistent about it, because the sky is vast and it's all around the scene--it will bounce its blue onto everything in the shadow areas, unless there's strong ambient occlusion or other strong colored surfaces nearby competing with radiosity.

Thanks! I adjusted the character and secondary object placement and eliminated the blue reflection (both things I didn't think of). As for the symmetry I'm confused. I included the render I started with and a screenshot of the mesh from the top view. I myself was curious so I went in and double checked to make sure it was symmetrical and it is. Is it possible that maybe you don't like the camera work specifically? I see that in the render it seems asymmetrical if you do what you described. I use renders specifically to avoid these types of issues and then am told it's still wrong and I need to learn a whole new set of ideas. I'm not sure what to do about that. Thanks again

I think it's because your model wasn't smoothed--look at how the inaccurate spots in your concept corresponds to the unsmoothed flat planes in the 3D version that are supposed to be perfect curvatures. Also, if you created a perfect oval shape with the marquee tool and overlay it on your concept and try to match, you'll find there are little bits here and there that's straying away from a perfect oval enough to look a bit rough. (even if you tilt the oval shape to match the angle perfectly).

Wow...really trying to see it. I feel like with this one below it's throwing away the angle/perspective and simply flattening it.

Is this below what you mean by an oval?

What are the inaccurate spots specifically? I don't see it. I appreciate the help and want to learn. I don't want to always have my paintings turned down for inclusion in the gallery. I want this. Having said that this is my best effort with my eyes and I don't see the problem. Where do you believe it should have been smoothed? Is it the cone-shaped part below the center-piece and above the bottom structure? That understandably should have smoothing groups on it. I just figured I'd paint over it and it wouldn't be a problem. One more try: below I re-painted this section after seeing a slight inconsistency with the render. Is that what you meant that I needed to follow the mesh more closely?

Attached is the problematic area circled.

I flipped the area horizontally on the left, so you can maybe spot the problem more easily, and on the right, the spots are circled. The problem is that they have a bit of an angular look to them--just enough to make the overall oval shape look a bit off and asymmetrical from one side to the other (even considering the slight perspective tilt). This is likely because you didn't smooth your model so that perfectly round shapes are in fact, perfect round.

So, no, I wasn't talking about the stuff elsewhere. Those are ok since they were adhering to the perspective.

If your goal is to get this piece into the Showcase Gallery, then you'll have to go beyond just fixing technical stuff--you'll need to strengthen the entire artistic presentation. When you look at really good concept pieces, the entire thing is painted so that even in areas that aren't the main focal point have a strong artistic quality. I'm not talking about level of detail, but artistic presentation. For example, can you crop any area in this image and it'll contain enough artistic presentation to look interesting? When you look at a Craig Mullins piece or some other famous concept artist's piece, you'll see that no matter where you crop in the image, it'll look artistically interesting, with compelling brushwork, or interesting lighting, or clever selective detail, or entertaining color variations...etc. Even in areas that are sparse, this is still true--that's what makes a piece of concept art more than just a functional pre-production image used for production purposes. You want it to become a "painting" that could standalone as a piece of artwork.

Great. I can fix that no problem. Thanks again.

That's a lot of good advice to take in and think about how to achieve that quality of work. I suppose I need to go beyond "It works" to "It works great!"
