I am working on a new Sonic painting. I haven't done one in a good while and this is my most ambitious one yet. Here's a rough layout of what it will look like:

The blue coloring you see is just to differentiate the background from the characters. And the darker shading in the back won't really be that dark, it just happened that way when I was making the patterns. I almost thought about throwing Eggman in there somewhere, but I think I won't. I was thinking about adding some rings in the loop and flowers in different spots, but I'm not sure. And should Knuckles be frowning or smiling? Also, I'm wondering if the water should be light blue and the sky dark blue/purple, like it was in the games to make Sonic stand out?
Feel free to comment or make suggestions. Thanks.
