Your latest one is a VAST improvement
. (Thats right, I have three thumbs, I dont make fun of your birth defects, so leave mine out of this.)
I really like the tiny one, its dead on. Both manage to look feminine without moving over into the sleazy department.
My critiques on the second are pretty basic, and shouldnt be to hard to fix.
1. The face could really do with some more shading, or a more muted skintone. I would honestly go with both, maybe shift the color a little bit further towards yellow and gray, and add some highlights (mind you, dont make it yellow and gray, just move in that direction a smidge from the color you have.)
2. The pose is a little bit awkward. I feel like maybe if you moved her stomach a little to the left it would do wonders on it, and Im kind of unclear if she is facing towards me, or to the right. The line between her right arm (well, my right, her left I guess) and the torso suggests she is facing to the right, along with her foot, but the rest of her pose and the proportions are dead on looking right at me. You could probably fix that a little with some well placed shadows, but really you want to work on the overall form, and make the furthest away points scaled down a tiny bit.
3. Her pony tail defies gravity. Im assuming that is a pony tail, although Im not 100% sure. If its hair flapping in the wind, it should be a little more exaggerated, and going up higher, otherwise, it needs some gravity applied to it. Right now, it looks kind of like she jelled it straight back, and thats a little confusing.
Otherwise, this is awesome. You have come really a long way on this in not a very long time, so my fourth thumb goes up to you
(dont ask.)
