nice shot. if this is not a crop, excellent shot; it's hard, i know. while i do like the combination of the purple and green, they create somewhat of a cognitive dissonance, because they are not natural... especially the purple spots on the rider's suit. 9.
I'd like to see your surfer more in focus as opposed to the water. I know this is basic editing, but it'd be better if you water was green and had a touch of blue. The green is carrying over to your surfer making him look green.
