1st image:
I like the pose, it's very feminine and the choice in colour is nice as well.
2nd image:
Excellent shading although I think the face is a little off.
3rd image:
Nice pose again, shading is nice, although it might be a bit flat.
It's also nice to see you draw a character that is "normal", as opposed to muscled up. Of course there is nothing wrong with a bit of muscle but as they say variety is the spice of life.
