I think you chooce the hair colour well.... imagining that it's white or grey-ish white like some ppl colours his hair seems.... weird.
So far...i think this is the most natural looking colour for Sasori what I've seen.
heh.... why does he looks so bored XD hehhe.... how ever I really like the expression. He's all like "I'm gonna turn you in to a puppet, goddammit!"
and very well coloured *admires*
