I think its good enough- pretty interesting too. I definately agree with above comment about the chain, it does need more 'weight', also perhaps the shadows across her body not quite so dark and dense ? Maybe some grid shadow on the floor too , beyond the gate to give the whole scene some more depth. But definately good enough .
