Uhm....not a flattering portrait, it makes his head look too large. Why is he looking out of the frame? It makes me want to know what's over there! Back up, Zoom in and have him looking into the frame are my suggestions.
His tightly pursed lips, sideways head angle, and heavy eye cut (with all that white of the eye showing) all combine to make a very unappealing look in this photo of this young man.
