Well I woke up pretty damn early on a saturday. -ahem- 7 am. D:<
I had a little spark of inspiration. I was looking through some Kingdom Hearts pictures -total nerd- and I just love Sora's Halloween Town outfit. Hence forth the mask on Shiko's head.

This is just a sketch, not the final product, though I added some gradient in there. I hope you like! I haven't shaded with mechanical pencil in a loooooong time.
