Pikmin 2D mockup

[Monobrobe]

I think you'd be better off getting rid of the top-down perspective altogether, because the only part of the image that looks top-down are the bumps at the bottom. Everything else looks like it's from a slanted view, so it's very jarring. I think you'd be saving more time just by editing the bumps at the bottom of the screen.

I hope that makes sense.
