You pushed she shadows, which resulted in making an already noisy photo much noisier. Also when you push the shadows like this things tend to get a bit wonky looking.
If it were my photo, I would have passed by it.
If you shot in Raw I think this is in the realm to fix and look good, if shot in .jpg at what I suspect is a decently high ISO....its probably not going to get fixed with any measure of quality IMO.
