Levels are spot on Ian!
The crop looks great. The eyes are the focal point of this shot and they need to really grab your attention. Try lightening the eyes a touch to make them stand out and then apply a dab of white paint to the catch lights in the eyes which are already there, but just need accentuating. Good catchlights really draw you to the eyes and add expression. Dab the catchlights with the soften brush so they're not too sharp.
Just gives him even more attitude!
