A break from animating

I took a break from animating and did some color sketches. These are probably going to look oversaturated on other computers; my monitor seems to be a bit wonky, color-wise. I already see a lot that I want to change, but take a look. It's turning out to be challenging to pick colors for the guy because they have to work against the ground and against the wall. I might go with what I have in the animatic and make the ground a similar color to the wall.

I used to want the whole place to appear to be made out of dirt, but now I'm not so sure it matters. I kind of have gotten used to the yellow look.
