Nice moody portrait. One little niggle though and thats the two white spots on his jacket. They catch your eye straight away so maybe clone them out. Think it would look better then.

Nice shot Tom but there is a bit too much dead space above the puffins head. Probably take about an inch off what i see here and then a little either side.

Love the bottom half,but the sky is way too over gradded.The light at the bottom is stunning.try using less grads next time you see something like this as i think it could be stunning.
