Quote from keresits a bit way too clean and simplistic. impressive for being a "noob" at hand painting. It doesnt quite look like a right texture for a mall, but it's definitely a start. you could try playing around more with the transition from the white to dark places. right now its just kinda a single perfectly straight shadow.
Thanks. I'll try to add more detail, but it doesn't appear as sharp as I want it to be. Oh and if someone wondering which engine i'm making that, it's Source.
