The bottom 40% doesn't do that much for me, so I'd consider cropping just below his hands to make a nearly square rectangle. I really like to tone range, detail, and composition/expression of the upper part.
Very good except the item he is sitting on. It is unusual and it makes one try to guess what it is and distracts my eye from the main subject. If it were a more common chair or stool then I would have to shut up.
The shadow behind him detracts from the shot. At the bottom of the shot there isn't enough contrast between the background and his legs, which tend to look awkward because of it. The striped thing he's sitting on tends to distract as well. Perhaps cropping just above the knee would have been a good idea. I like the pose, but it's hard to see the details of the face and such. Perhaps a closer shot with a horizontal orientation would have worked well. Overall this is a good shot, but it has some detracting factors to it. 5
Good shot of an interesting looking gentleman and a bottle of wine. I love the tones and the subject is good. The focus and light are also very nice. I just wish you were closer to him. Good job, congrats.
