A lovely image. Beautiful light, background to die for, detail, exposure. And a nice pose. Some may say a bit tight in the frame, but I like it as posted. I might consider brightening the iris just a bit, and I'm torn about the bubble in front of him, but would probably leave it. Slight sharpening halo below the bill.
Nice colors in the FG and BG. You need a little CCW rotation. The best way to straighten your horizon on a photo like this is to line up your legs perfectly with their reflection. You have good exposure here and nice details but it appears you have oversharped the image just a little.
Very nice indeed, I agree a tad over sharpened in parts. I would definitely brighten the eye, and I would use the ruler tool on the water ripple to straighten the image.
