I did 2 more variations on the background of my level. One has the saturation a bit down as well as the contrast, I think the ball mixes in too much with the enviro on that one. The other one has the same floor pattern as before, but the concrete has been darkened, and the ball lightened a bit, I think this is much better.
Only concrete darkened
This is where I will be posting my modeling and texturing exercises, as well as any general CG related things I do.
