..new layer: overlay - to get a better idea of what this guy's local colors are going to be.. at this stage, I tend to spend a lot of time referencing/experimenting with colors to see what works..
alright, so next I'll throw some lines on there to get a feel for what the shapes are going to be (it's not uncommon that I may use a couple of layers for this.. a rough and a cleanup.. sometimes I spend quite a bit of time on the drawing, but I was lazy today)
..and less hard edges..
...I think it needs more contrast at this point..
.. cropping in I can see a character in some of the shapes...
