Wow, this is really good! Everything's very distinct, you did a great job with the design. I really like how all your palettes are really dark, but they stand out from each other enough to give your skin a definitive design. The backpack in particular looks awesome. :D
If you were to change anything, I'd suggest the arms and the legs. Putting shadows on the insides of both of them (where the arms touch the torso and where the legs touch each other) can do a lot for the form of the skin in general. It can take a little bit of fenagling to get the legs to look not weird, but I believe in you. ;P

Oh yeeeees! I love this song! :D
The skin is amazing! <3 I love the way you did the hood and hair.

Haha, I remember when Myra was a pair of trousers xD

I love that song so much ^-^
