Love it! The pose is interesting. Your anatomy is brilliant. However, when I first saw the 2nd picture, I thought the character was really short as if it is small creature (ie; halfling, goblin). Well, I don't think there is nothing wrong with that. She is a goddess after all. She doesnt need to have a normal human proportion.
Oh and regarding the pose. I'm not sure what you have in mind. To me, the first picture suggest the character is jumping and ready to strike with her mighty sword behind her back. But after you completed her body, I thought it looks as if she is dancing, which I think will go a lot better with a happy/cheerful expression.
All that I said are just my thoughts. I honestly don't think there is any fault in your design. You don't have to change anything. It is unique and interesting. And I like your style of painting too. Looking forward to the finished product!
