Love your composition... offers a lot to work with.
Using CorelPaintShop Pro ... was able to quickly work up some possibilities ~
1- Blurred and cooled the background.
2- Warmed and sharpened the foreground golfer and golf bag.
3- Added some shadow tones on the right and left side of the vest.
4- Because of the unifying color of the trees and fairway - green ...
had to change the vest color to a high yellow-green ... to obtain
foreground - background seperation and 'pop.'
5- This is not the only way to obtain 'pop' ... but it is a suggestion.
