From my indie days
The image above is concept art for a racing game that may or may not still be in development. Painted over a screenshot (but you can't see any of it anymore). The pixelized texture is meant to imitate the nearest-neighbor interpolation algorithm commonly seen in PS1-era 3D games.
I made the background and the platforms in this game. Took me a couple of hours.
For some reason, it didn't tile properly. I also drew the monster on the top right corner.
I painted this in GIMP while snacking on delicious wafers.
Concept art of a martial arts "monkey warrior" for concept approval and 3D modeling.
For games that I wrote code for, check out Videogames.
