God Damn, this one took ages.
My older brother loves TMNT. When I found this template, I immediatly thought of him, and asked him his favorite. Of course it wasn't Leonardo...since Leonardo is kinda a prick (it's Rafael), but my brother wanted it anyway.
Long story short, this is my second shot at him. The right arm took about 5 or 6 tries, but its done. And its fucking awesome.
