I apologize in advance, I'm going to proffer a strictly honest opinion and hope that it's valuable to you.
Frankly, I don't like any of the images much at all. Of the ones you posted, I suppose the blue-tinted one is the best, but even this one suffers from being over-exposed (the hair of the man on the right bleeds into an overhead light), and the overall 'soft glow', blurred look of the picture feels trite and uninteresting. I would enjoy it a lot more if were sharper (otherwise, I like the composition).
I'm not sure where to start on the others. Honestly, I'm not sure what you're going for, so it's difficult to make a poignant criticism. The initial portrait you posted (while I like the subject) isn't very good. It looks as though you used one, very harsh light-source, blowing out half of his face with white, and blackening the rest. The 'soft glow' feels cheesy, and looks awfu, especially when I notice that the collar is still sharp.
The last picture you posted is a joke. The hair looks awful. That said, though, I think the grainy/'soft glow' feel succeeds much more in this picture. It almost feels a little bit like how a scan of a very old, blurred photograph might appear today.
I hope that was helpful.
Always remember that no amount of photoshopping can save a bad photograph. Having not seen your original pictures, realize that I'm not saying your originals were poor, but this is what your photoshopping suggests to me, and I think that it's an overall important consideration to maintain.
