#3 is not a keeper at all, IMO.
The branch at his head is a shot killer for one. Make sure you're checking the edges in your viewfinder.
It seems noisy to me. Since you said there was no PP, that tells me you had the ISO cranked up. I would suggest using a tripod and keeping the ISO down so you can use the longer shutters without having to handhold.
Model certainly doesn't look like he is into being photographed at all.
#1 doesn't really trip my trigger. I don't really have much to say about it good or bad. Maybe a different angle or gesture, I dunno. But I will say that the puffy shirt makes her look knocked up. If she is knocked up, that is dandy, but if she isn't, I doubt she would care for the shot much.
#2 is good to go. It does remind me of a clothing ad as others have already mentioned. Considering that sentiment, it might be getting to be a worn out style and will loose favor soon. Left hand seems a tad awkward, but that is a minor niggle to me. Most of the power is in the posture and facial expression in this shot for me.
By the way, don't climb someone's tree when they give you a critique that you yourself asked for (by virtue of posting in this forum) simply because you disagree with their findings. If you don't want honest feedback, stick to the gallery forums. That person took time to review your work, form an honest opinion and type out their thoughts for your consideration.
Fresh eyes and a different perspective are two of the most valuable tools a photographer has, and they only way to use those tools are by showing your work and seeking opinion.
If someone tells you that your work resembles a hat full of smashed buttholes, but then tells you why, smile, nod, say, "Thank You." and consider their opinions based on the individual rather than what the individual had to say.
If Larry the Cable guy told me that he really enjoyed my nudes, I would appreciate the comment but lend it little credence, but if Jaques Sturgis told me they needed work, I would be crushed and rushing to the drawing board.
