Sweet stuff. Kinda' feels like something from Osmosis Jones.
Well. This is... unusual. And interesting. It has a bit of a late 90s comic feel. I like how the colours are all relatively the same base, just darkened and lightened. That said, the contrast is too little in this for how large the image actually is. The maroon linework doesn't seem to lean in the favor of the weak shading either, causing your eye to see more flat colours rather than the subtle palette changes you have here. Drop some dark aquas on the back side, add a tinge of sickly yellow to the highlights, and this could go from mediocre linework with slow colours to a real study in contrast.
