It's too dark and i don't really see the "vintage" thing in your editing. Sorry.

interesting landscape! (perhaps because of the "darkness" - I like this light!)

thanks for your comments

I think its a little flat, the clouds don't enough character for the scenery to stand out.

Thanks for your comment. You are right, i thought the same thing but i was affraid of letting to much sky.

I agree with Jenseye for the bottom of the picture. The sky is nice (maybe not contrasted enough)

not sure if you used a polarizer but that should do the trick with the sky

Thank you all for your comments.

Nice sky, though a bit noisy. Some more contrast to make the "weird-looking" clouds pop out would also be good.

I kind of disagree about the bottom of the picture, I like it, sky-only shots can get boring very quickly. But the problem here is that it's extremely soft, almost out of focus.

Sharpness and lightness miss the picture.
I don't like the framing , too much "empty" sky.

thanks for your comment,Kamaki.
you're right, too much empty sky.I should try another time.

Im with kamaki. Play with Shadow/Highlight in PS. Maybe it will help.

I think the amount of sky is just right. It could use more contrast, though. Overall, interesting composition.
