Colours feel somewhat awkward... The bright parts of his face seem too bright, while the darks feel exaggerated. His neck seems weird, rather busy and dark. There is too much empty space, particularly in the right. The text is nigh unreadable, it is placed to far from the focal and it has little visual continuity with the rest of the sig. Lighting is mediocre, though there is a GENERAL direction of lighting, it is highly unspecific, and not perfect. There is not much going on overall, and not much to catch the eye of someone.
