[edit] Since this is on a new page, I’ve added a scaled down version of the original image so you don’t have to back and forth to compare it with the other one

Koryh, this picture is so great! In regard to your comment about 3d stuff hurting your eyes, I fully agree. I am guilty of creating offending images myself, mostly because I don’t start the image from a whole composition viewpoint - I focus on the cool stuff I’m going to model for the scene. Composing the scene is secondary. Another issue is trying to be photo-real. This leads to lack of control over the image.
I hope you don’t mind that I did a little breakdown of your image to show why it is so good. Please feel free to add any insight you have about why the piece works so well.

First off, this is KOryH’s image with the Brightness dropped way down and the Contrast turned way up. This makes it easy to see the shapes in the image.
In any image, the viewer’s eye is attracted to points of high contrast; the brightest bright next to the darkest dark. Notice that the light coming from behind the trees is bright. But nowhere is it as bright as the glowing light floating above the stone circle. If they where, they would fight for attention, keeping the viewer from knowing where to look. So, with light and dark values alone, KOryH guides the viewer to look first at the glow over the circle of stones.
That’s a good start, but notice the red arrows I’ve drawn over the image. These show how the shapes in the image direct the viewer’s eye back to the circle of stones. Also, if the tree were straight up and down, and the horizon were straight from left to right, the image would be much less dynamic; less interesting. Also, if they slanted down towards the edges of the image, they would lead the viewer’s eye away from the stone circle.
There is one rule that KOryH does break. The “rule of thirds” recomends that the center of interest not be centered in the image. It suggests that the image frame be divided into thirds, and that the focal point should lie at one of the intersections of these dividing lines. Since KOryH’s focal point is centered left to right, but not up and down, it isn’t too noticeable. This problem is also very easily fixed by a little cropping.
The last thing I want to point out is the stream. Look at its reflection. At this angle it would probably reflect the bright light from the background all along its surface until it ran off the bottom edge of the image. This would lead the viewer’s eye straight out of the picture. And passing as close as it does to the center of interest, where the viewer’s eye goes first, the viewer would be quickly led out of the image with no chance to appreciate the rest of the picture. Wisely, KOryH darkens the stream as it leads to the edge of the picture, turning the viewer’s eye back into the image.
It is this third point particularly that gives us 3D people trouble. Many think that if the render came out like that, then that’s what the light would really do and, therefor, is what the light should do. Wrong. The result, whether from 3D, 2D, or a mix of the two, is a 2-Dimensional image, and all the rules of good composition apply.
Perhaps you have seen the short called “Bunny” , the first short to be completely rendered with radiosity. Radiosity is supposed to be the most realistic lighting model available, and should, therefor, create the most realistic images.
What the team found, however, was that the realistic lighting bounced into places where they didn’t want it. If the background and the character have good contrast, the character will easily focus the viewers attention. if the contrast is low, the character doesn’t “read” well (doesn’t attract the viewer’s eye enough), and this is the problem they were getting. The background fought for attention with the character, causing the images to lose focus.
They had quite a time tweaking the radiosity to get the realistic look they wanted, yet still keep the light from messing up the image. They did a fine job, and looking at it you would swear the lighting is natural. But it’s not. They carefully followed the rules of composition and contrast even thought they had to bend the rules of how light behaves to do it. Because they did, the piece is very beautiful, and visually powerful, just like KOryH’s.
