Awesome, you really nailed it. The colour spectrum is very well chosen I would have been afraid that the colours would meld together too much, creating a indistinguishable mess, but you`ve managed to make them distinguishable, all while keeping in touch with Plutias colour palet at the same time. Of course I don`t know much about the intricacies of skin making, even thought it does interest me. I just draw manga/anime characters from time to time.
Anyways great work!
