I think tbhockey's right: there is an amount of fakeness, so, if you edited it, maybe you should try something else, if you didn't perhaps reduce the glare of the sun in the very top right corner, leave the rest because it's beautiful! Maybe it's just one of those photos that's to perfect to be real. I love it, though.
The world is changed. I feel it in the water. I feel it in the earth. I smell it in the air. Much that once was, is lost, for none now live who remember it. -Lord of the Rings, The Fellowship of the Ring
i think the "fake" feel mentioned afor could simply be avoided by the placement of the light. it looks more like you are opening a door in your house and letting the light in than like you are seeing the sun peak around the mountain.
the truth is, i liked the image so much that i faved it. i think that it's easy on the eyes. i could look at it for hours think it was time well spent. good work.
