I have done many icons for several games. I will occasionally update this page with some of them.
I typically have created icons at-res, usually 64x64 pixels, with the goal to control each precious pixel. However, I'm finding that I do better when I work larger, keeping a smaller scale in mind. This lends itself to a less cartoony feel. I'm also discovering I'm actually faster if I work larger. I'll share a process at some point down the road for artists who are interested. Small as they are, there are many many ways of producing a successful illustrative icon, so I'll share a few approaches in the process section of this site. Check back to see.
