The next image is of a tiling rock wall I did in about 2 days time. I wanted to create a game asset that could be used modularly. Overall I think it turned out nice but I would want to do another pass on textures if I ever put this on my portfolio.
This last image is the current project I'm working on. It's not for school but just an exercise in composition and quick level building. Not sure if I want to keep that alien in there or not. We'll see. But it definitely needs more stuff in it, right now it looks kind of bland.
