Really interesting shot which makes me want to know more of what is behind it. Possibly a bit of cropping of the foreground would work, but then again is does convey a feeling of emptiness. Lots of questions...
Your sky and the tower are very interesting, but the bottom part is taking way too much space in the overall picture and has a lot less interest to me. You may try cropping a bit or getting a bit closer next time.
By giving even treatment to the sky and land, this image seems to have an identity crisis. I think you would have a stronger subject if you had chosen to emphasize one or the other more significantly.
