haha awesome

That's a pretty cool one. Although as detailed as the colouring on the face is, it's not very distinguishable when looking at it from a distance, the colours blend into a grey hue for the whole head. Anyways, the colouring is what makes it a good drawing. Personally, i think it wouldve looked better with vector outlines, not black ones, but lines with the same colour as the colouring so it looks nice and smooth. But yea as you said, no point in reaching perfection with this, there is a point when you're just tired of it and wanna move on;)
