Hey! Thanks for your comments Joe, I had problems adding light to the character from the spell because of the limitted palette (16 colors), I tried to add highlights but couldn't do it without ruining the drawing (any hints on how to do it with the colors used are very welcome!)... Also, I agree with the scarf/cape issue, I should've made it more wavey, I'll see what I can do to fix it. Thanks again!  

The shape of the fire is great! Outlines might benefit from being a bit darker. The shading on the scarf kind of makes it look a bit embossed at the moment, whereas it could be more wavey if it curved a little more and has greater lighting changes at the waves? Perhaps you could also add a little of the light from the fire to the character, too?
