Well, cropping suggestions are the ultimate unimaginative critique, so I thought I'd ask before wading in.(posted 8303 days ago)If this were my image I would crop it just above his arm, but below the lowest button. I would also take a sliver off the right side to maintain the tall-thin look, which fits well with his physique. The light on his face is so good it should dominate the image without distractions, and it's clear from his expression that he's relaxed, so you don't need the hands to show that.
I would also burn in the horizontal end-wood streak just above the peak of his hat. It's fighting with the frame more than with him, but it's distracting nonetheless.
