This is a beautiful scene Cyril, nice capture! *As for critique, there are a couple of changes I'd probably make. First, I'd get rid of that white stuff above the trees in the background. If you're using Photoshop, one simple way to do that is to use the Eyedropper tool to set your foreground color to that of the sky color directly above the particular white area you're working on. Then, using a soft brush with the mode set to "Darken", simply paint over the white areas with that blue color. Other possible improvements might include brightening the sky a tad and maybe even cropping a little off of the left side, so the trees are not quite so centered. I've put my try in the Demo folder but with the full sized file I'm sure you could do even better. This is just a few possibilities you might want to try, the image is very nice just as it is.
