I chose to draw some existing characters to begin with when experimenting with colours. In the past, I've chosen simple tonal shading instead of colour because it ended up ruining my work and consequently meant hours of wasted work.
I chose to draw Perfect Cell (due to my preference to drawing villains, c'mon they are much more fun!) This shot is actually one that I freeze framed from the show and sketched. I think it really captures the moment of rage, frustration and fear when Cell realises that Gohan is far superior to him.
