First Impression - the most important one: I hate gold .. what is the point .. chasing a little white ball around a aeries of green fields ... but hey this is a great shot ...
Composition: I like that you have cropped in this manner ...
Subject: Meets the challenge, person in environment .. which tells story.
Technical (Colour and light): Lovely natural .. and all that ... his face seems to have a little much colour added post processing but hard to know without knowing your processing steps.
To grow its vote?: this shot did great ... you gopt top 50 percentage ... that is good ... I can also see that this is a stretch from your normal pics .. which is really cool.
Summary: Keep it up you are doing well.
Interesting to do a critique on your image but it is difficult if you don't give us any information in your photographers comments. When we do a critique, we go past just the photographic result, that's what voters comments do. The critique looks at what you were trying to achieve, how you wanted it to look and what issues you had in getting the image captured and ready for voting.
If you've got any questions about this critique, please feel free to contact me via the PM system.
I enjoy this image and the clarity in it. It sort of looks like there was too much dodging on his face... maybe not though. Alas, if that was the case too much shadow would at least look more natural than too much dodging. Still a pretty good image.
This is actually a candid not a portriat. A potrait indicates the subject should be posed - in this challenge the posing would be done in his/her environment. If this man's environment is a golf course, then perhaps you could have had him pose with his clubs, or along side the flag.
