Also quite nice. Something about the angle of her arm/hand bothers me a bit also - with this crop at least. Very nicely lit. I would like it better if you could take just a bit of the pink/red out of the corner of her eye, but only if could be done without it looking unnatural.
I cheated and looked at all four before coming back to comment. It's a lovely model and photo. For a way it could be better, her hand being half cutoff bothers me some. The last of the series is better in that respect. If this was cropped, perhaps leaving a bit more on the right, and therefore placing her eyes lust left of center as opposed to just right of center would make a better composition.
