I'm not real clear on the sport portion of this very pretty photo. Is it the guy in the kayak? Or is that person shooting? (these are rhetorical questions)
Nice clouds, reflection is nice except a little overdone, interesting bridge... hard to tell that the guy is fishing tho. What is the round thing above the pole?
Choosing the sky was a good choice here, as your silhouette is pretty striking. Not sure about your distance to the subject, but maybe firing a flash to fill in some detail on the bridge would improve the transition from light to dark.
But overall, great shot! Especially for basic editing!
