Looks amazing man, this is really great work, but what did really stand out was the foreground, it's really distracting. Maybe make it a bit darker with a few highlights where the sun would hit or make them a silhouette? This would also definitely benefit from a bit of blur, that'd create a nice depth of field effect, it's so detailed at the moment my eyes don't know where to focus.

Like in this poster, the blur leads your eye to the focal point more, so in your image would be the 2 statues at the back.
Other than that he rest of the image is brilliant, hope this has helped in some way.
Cheers
