Eeek! Elven Unopa
is scary! Humanoids are bloody difficult to get right, so I wouldn't worry about it. As Dequibenzo said, Rembrandt was still learning how best to draw humans when he died, and he is supposed to be one of the grooviest portrait painters ever.
I like her boots and cloak, though.
The hair is nice and anime-like as well.
I like the Voltian pic; I think you're putting yourself down there. The highlights are excellent (I'm still learning how best to do highlights, and I can hardly do them at all by hand yet). He looks like a character from Dynasty Warriors 2. Verra nice... keep up the proverbial magna opus!
