Nice focal, eye appealing.. Work on your blending, he could definitely be blended in some around the shoulders. Text is nice but move it to the left side, you have some flow of effects going from the bottom to the NE, so the text kind of messes with that flow you got going.
Agree, ish, with Pink. Except the text doesn't work, anywhere, just remove it entirely. Other then that, prefered the coloured version, some nice effects, maybe need a more defined light source/focal point + like said he needs blending in better but, not bad.
