Nice colors and scene! You might want to straighten it though, the horizon is not level. Also, it might be possible to bring out more detail in the sky (clouds) by using a copy of this layer, blended to multiply (and perhaps masked to the sky).
I tend to really like pensive lonely shots like this. And this is superb. Focus, colors and overall mood are there. My only concern is the fishing rod. When my eyes follow it, it leads me right off the photo instead of 'into' it. Also, the fact he's facing something off-photo kinda throws me off. That aside, it's a solid 7 for now. Had he been on the right I could safely guess an 8.
I love the color and the horizontal lines. The horizon is the slightest bit off. Be very careful with that, especially when the horizontal lines play a huge role in the composition. Beautiful color. I love the simplicity. 7.
Horizon does not appear to be level and the water on the sand seems to emphasize that fact. Good job of placing the person on the 1/3 mark. Sky appears to be overexposed.
