There are several important things you must consider when doing a matte painting.
One is to establish a light source. The most obvious error I see in this piece is the inconsistency in the light direction. Look at your source image. Where is the sun? Itâs behind you to the left. However, in your composition, the sun is behind the buildings, which immediately destroys the illusion. You need to either pick a different sky or a different skyline.
Youâve extracted the buildings nicely, but the color balance is not working at all for me. Why is the sky brown? You need to develop a mood and carry that out consistently throughout the entire painting.
There is no sense of depth. The conflicting sky and buildings partly contributes to this. But also, it results from cropping off the river. The lower edge of the painting corresponds to the horizon line, which is pushing it a little bit, unless you were going to add more elements on top.
If you want this to stand on its own, you should consider developing a strong focal point.
So my tips are:
