Love his expression, wouldn't want to get any closer.

Now about that green stripe right across the bottom?! It is an artistic decision on your part to leave it in as it implies we are peeking into this handsome brutes world, it says PRIVATE, do not enter, yet thanks to your lens we have entered. It is artistic license to have left it there. The alternative would be to crop tighter to really show us his personality and this would be possible simply because your focus is dead on sharp. Good exposure with all detail showing and sharpness on the eyes which is critical in portraiture. Try a portrait format too to give him more nobility, which he already possesses. He is a most handsome fellow and looks like he's in love with your lens, or you. Great eye contact. Nice post.
