I dont think using the same design is bad, especially when it seems to be the same character. However, you can see the laziness with the face (cut+paste with some rotate). Also, ya that raised leg is super long. I have nothing against long legs, but the other leg is much shorter, even considering perspective, so it ends up looking wonky. The saving grace is the superb rendering and detail.
That far leg... could use a bit more work on making it attached to her rather than just being a prosthetic she set next to her close leg. Other than the part that I can't stop seeing that after I noticed it, the rest is fairly good looking.
I noticed that you took the torso from another version of this figure and changed some of the features, such as the legs and arm positions. I'd advise against doing this despite deadlines. As others have said, the legs look off. Especially the left leg.
