No, this isn't the finished drawing, because I'm not happy with it. I just borrowed it for a coloring template, because he's human and I wanted to refresh my skills at coloring human skin.

While these are both supposed to be Howie, the left is an odd variant, where he's actually half elf. I know, traditionally, they're blond, but I wanted to try a red head. Originally, he wasn't supposed to have a Speedo that matched his eyes, but I forgot about Howie's eye color. At first, I didn't like the effect at all, now, I'm not so sure.

On the right is his usual, exotic looking olive brown and black-haired look, only this time, it's human skin, rather than fur. Prae voted for this one, hands down, and I do admit to being very fond of this color scheme, myself.
