Good use of centering of the main subject. However, I'd rather have seen more of the interesting paving than the over processed, undramatic sky, which would have compensated for the lack of strong light. Your wide angle lens would have made the view very impactful and prevented the centred horizon.
Very nice image (i just feel its A BIT tilted - maybe its an illusion, or maybe its just emphasized by the symmetry, or maybe it is really a bit tilted). Anyway, i'm still giving it a good score.
