The first image is wierd. What exactly is she supposed to be? A robot?
What is the thing coming out of her forehead?
The pisture look flat. There are no varibles in color, shadows or highlights. And you light source is all over the place. Where are the highlights coming from.
The second, where do I even? Her head is too small for her body. And that thing on her head! What is it? is it a horn that got sawed off like hellboy? The lighting is all over the place, dark shadows in the upper right, but her shadow is right below her highlights from directly above, if this were the case, her shadow would be much darker.
The anattomy is very in accurate. Are those supposed to be muscles or is she wearing armor plating? why is the darkest shadow in her spine? It shouldn't be that deep. Her breast look like wrinkled deflated water balloons, and her skin has a leathery look to it.
I don't even have time or want to waste time on the feet (Hooves?).
I really don''t think you have enough free time. You should study anatomy. I don't think your porn collection is helping much.
Hope this helps.
