I like it, maybe not enough that you should put it in an exhibition, but certainly enough to be glad you’d brought your camera to the beach that day. His expression could be better (eyes closed), but you caught the action well. Post-processing could pop the colours a bit but in the middle of winter you wouldn’t expect bright sunshine or anything other than a grey day. I’d go for a tighter crop too.
The text you’ve put on for the title and your name are a bit much, as has been said before, and probably isn’t necessary to prevent your picture being stolen and used to make millions.
