sTyLeS, I did a quick overpaint of your current derby piece. I think the execution was great, you picked good colors and followed your established light source.I’m here to offer you an alternative lighting scheme, to help in a story telling and general design sense.
In your version, you have the light coming in from the left, with all of the shadows facing right, while your punchline is on the right side of the design. You’re brightest most saturated color is leading the eye away from the punchline.
Do this: Close your eyes then look at your design. Where is the first place your eye wants to look? Is it that big clump of color on the left? That can be fixed, by shifting the light source to between your “weebles”
In this overpaint, I put the light source in the middle of the figures. I also cooled off and desaturated the shadow areas and added a little secondary light in the shadow areas to round things out.What this should do is draw they eye more toward the “action” and help the joke read a little better. I probably could stand to tweak things a bit more to help the focus, but I think this at least gives you an example of how to do something a little different.
When I talk to young colorists the biggest issue is what I call “pushing and pulling”. Meaning, you need to use color to push some things into the background and pull other things into the foreground. Cool color and shawow will recede, while warm colors and light will come forward. The further the viewer is from an object the lighter and more desaturated it becomes. Look at the better designers here, they are masters of these concepts, and create designs with amazing depth and focus.
