Fiddling around with colouring, this one didn't work out so well. But blue is very pretty... <3

I do like the effect of having the original sketchy lines visible under the lineart, but it only really 'works' in any sense of the word if the sketching is the same colour as the final colouring. I don't think it will work at all well with a multicoloured character. Now that I think on it, doing detail lines like that might be an interesting idea to try...
