Deleted, had much transparent brush and too messy.

Yeah, real messy! Done fast for avatar since I can't use my regular one here.

The lineart is pretty messy, and color count jumps dramatically when things get red. The first can easily happen if you're working at a higher resolution and then rescaling down without filtering - it's best to work at target size straight away so you don't have to scale at all. The second might come from using transparent layers or a brush with partial transparency, which easily blow your color count up and can make things look messy.
