after it has color i think the fact that it looks like other things will go away, as far as colors to add I would do bright vibrant ones like oranges, greens, yellows, blues, ones that really make it pop. just my idea, good luck with it
ahh now i can only see the sex doll gnome! def add color or shading or something so that it doesn't look like that anymore!!! i feel bad for even saying that but it really does look like a weird little sex creature
