C4D helped it (a little, but now it is a little messy but shouldn't matter). Remove the 1px yellow border, makes it look stupid. I like the general idea of it, but I don't like the style. Render could be blended better, try smudging parts of it. Maybe a gradient map or a photo filter will sum it all up.
Nod bad.
On the avatar: Nice and simple, but pen tool isn't done that good, imo.
