First 1 - focus is nice, framing is pretty good, exposure is great. I don't like the white petal hitting the side of the frame. I am not sure that the green leaf over the top is working. I think it would be better with more space on left and no leaf over the top.
2nd - good position in frame, nicely exposed, good eye contact. I think it would be better with the guy a bit higher so gravity has more feel. Perhaps if possible a bit more close in so he takes up a larger portion of the frame. He does not look overly sharp.
3rd nice exposure, great colors, good depth. A little bit too centred. I would subdue the white lights in photoshop. Frame a bit more left and down might improve.
For me 3rd is best but 1 would be best if the flower was not up agains the frame.
I had not noticed the framing on #1 and agree with every point you've made. Need to revisit that crop. Also, the intrusion of the leaf, the more I look at it, does not work for me.
Perhaps another session early this evening as the blooms are nocturnal, attracting luna moths.
