nice photo, but I think it's a little too dark, the sky seems good, but you can't see a lot from the valley.

I agree with the above comments. I'd love to see this same picture taken on a brighter day so that the sky would be blue and the colors of the vegetation would show. The shape of the mountains are very interesting.

I like the photo but the problem has already been stated. It appears to me bright vibrant stuff is more admired then the dark rainy clouds... I like it personally but even I think it is a bit dark... Overall great scene though just maybe throw it in photoshop and brighten it up a bit and see what you can do about maybe throwing in a light source. keep up the great work I admire the shot!
