Still looks a bit off to me, I'd say loose a couple of the spikes and attach the skin between the wing bones (?) to the body as CGPMaya84 said...

Also, I think you might have overkilled the spikes a bit... I think you should try to make them a bit more "random", maybe by removing some of them and adding them with som different intervals (different and more random spacing between them, if you know what I mean)
