A very restfull scene
i like the way the boats are arranged in a line and the color in the sky overall just a few things i would correct:-
1) The image looks very noisy....have tried to reduce it in the mod but the output is not very good largely due to the uploaded images lo res so the sky looks a lot softer than i would prefer
2) As it stands right now i think the sky and boats compete for attention, in the mod i have cropped a bit from the top to bring balance.
3) The image right now looks a little flat and could do with contrast especially to bring out the sky better, in the mod i have attempted this
While i havent done this in the mod you may also want to try cloning out the boat in the middle to see if it improves the shot
Hope this helps, i i think if you try the above on the original image this would carry a lot of impact
