I like the 2nd version better. The first version feels too sharp & the highlights are distracting.
I really don't like the crop/composition. Her one elbow is right on the edge of one side, while the other is not. Also, there is a lot more room above her head than on any side of her. It just feels unbalanced. Of course, photos don't always have to be balanced, but it's still a good idea in some cases.
The lighting looks pretty good with the strong back/accent light etc.
Maybe a small critique...and I think it's something that applies to many of the photos that you put up on here....it just seems to be lacking 'finish'. For example, her hair is messy. It's especially noticeable because of the back light. It's got a funny shape on her head and we see messy stray hair in a few places...her armpit being especially bad.
I think you did a bit of processing on the skin, which is fine. But I think that if you had brought in good hair & make up artists, it could have given this shot the 'finish' that could take it to the next level. As I said, I think this applies to many of the shots we see from you.
