I'm bored. I like cropping pictures into avatars. Leave your faceclaim here and I'll see what I can do. You can leave slightly more detailed instructions, but nothing fancy. I can't recolor things, for example. I prefer to mostly leave the art itself alone, bar perhaps changes in sharpness, adding a background to things otherwise transparent etc.
I'll probably make a handful of whoever posts since I'm bored enough. It only takes 10 seconds to post your faceclaim in here, after all. Who knows, you could like what ya see.
