Good framing, showing all the headcloth. The subject and his clothing stand out well from the background, which is less sharp, is suitable for the subject, and not at all distracting.
Possibly the subject and clothing might have been made just a bit darker in tone, to slightly increase the contrast.
And if you had some communication with him, and could get him to tilt his chin out a bit, the shadow which is half over the left eye would have been reduced. However, a good environmental portrait!
