There is much to like here. I quite like the ethereal processing, it's effective and really very lovely.
The pose, not so much. It looks in this shot like she has rather poorly done implants, for one thing. Also, her arm looks INCREDIBLY TINY. Or maybe her head looks huge? Or something. Her proportions just look completely off here.
I think you might have processed her face a little differently than the rest of the shot? This might be making her head "pop" more, and thus appear enormous, somehow.
