Geia sou Andria and welcome to TrekEarth!
I like your photo but I think it is a little bit dull. The photo levels can be adjusted very easily with any photo manipulation software. I will do that for you as a workshop example.
Excellent photo! Love the contrast. Your photo acually motivated me to take a photo similar to yours today. Was lucky because the weather was excellent. Take a look at it here.
Excellent photo. Very sharp, depth of field just perfect and nice warm colors. The sky on the right is a bit overexposed but I know it's unavoidable (it happens to me all the time!)
