The top one has great presence and panache! Very good exposure control and balance with the background and the 'high key' look to her face works well. I do think the hands and fingers are a distraction though, perhaps more a negative aspect than a plus ....it's probably the particular shape and gesture she's making, something more delicate and refined in the positioning would improve if I think . And I'm wondering if having all of the flowers in behind visible would be better, rather than cut off on the right edge ....?
I'm assuming the 2nd one is your 'pullback' to show more of the setup......I can see there's light coming from her left and in front, it would be good for us flash gear geeks t know the details ....
