Fire And Ice (speedpaint)

This has dynamic, balance and very neat lighting. The characters are quite eye-catching and colorful and you can tell they've got more than a fair few tales to tell; I can also appreciate the cartoony style you're going for; its unique and quirky if yet not overly so. The clothes have a degree of realism to them that, perhaps sadly, overshadows that of their faces and their hands; it does make the piece look a bit less uniform and less of a smooth impact.
I do like this one a lot, but it can deal with a bit more refining along the faces and the hands, especially.
