First...where was your photo taken. It looks like a beautiful place. I really like the water and the boardwalk. The water is perfect and the walk leads my mind up the wonderful path. I'm not sure about the upper third of the shot. It's almost like I want to see the water and boardwalk from a higher vantage point. I stared at the shot for a while imagining walking up the path which I think is exactly the effect you would want this photo to have. Well done.
That's Vintgar Gorge in the Julian Alps of Slovenia. It would be fun to shoot from a higher vantage point, but that's quite impossible. It's a narrow, treacherous gorge, accessible only by the 100-year-old footbridges secured to its walls. Actually, taking photos there at all is rather tricky. It's very difficult to find a good spot on the bridges where a tripod won't completely block the path. I had a lot of people wearing backpacks squeezing past my tripod to get through. One of them caused my favorite pair of sunglasses to plunge into the river.
I like how the leading lines here take us right in to your subject. All of that sky isn't doing anything for the photo, though. You could crop in quite a bit on the top and right and thereby get us a lot "closer" to your subject (and get him that much further from the center of the frame).
