I think the hands work just fine. The scales on the other hand...over most of her body, they came out pretty decently, it's just on her face that they look a little off to me. As for the hair...it came out just fine, you're just being too picky about it. The icture came out pretty well. Though, next time, you might wanna omit the eyebrows.

The hair came out fine, I just don't like the style. =P And those aren't really eyebrows, they're eye ridges, and they apparently read better when I haven't drawn scales on. The face really should probably have fewer scales on it. I just wish scales weren't such an incredible pain to draw, or I'd try doing it a few different ways to see how I like it best.

I like the hair. The hands are well done too but to me they look more like they belong to a male rather than a female. You might try giving the thumbs a more gentle curve and making the fingers on the right hand a bit more slender. The fingers on the left look about like they should. You may also try elongating the scales a bit along the line of her body (up and down in this case) instead of the diamond shape they are here. I've noticed that snake scales tend to elongate pointing towards the tail. Just offering a few suggestions though I do like what you've already done here.

I love it! it's so cute! Hm.. usually the scales on the head are bigger and more oddly shaped than the other ones. Maybe exaggerate that? I love those kind of shirts, too, nice clothing on her ^^

I agree with Dharken; I think the hair looks quite nice, and perhaps you could slim up the fingers on the hands just a bit, but in general it looks good... except for the scale-pattern, especially along the arms; it doesn't stand out as much as the ones along, say, the face do. Though, honestly, the idea of putting more detail into all those scales makes me bonkers just thinking about it, so hey.
