I would only echo Buddies full review, so I will only add what I think is missing..

Not only would I go back and get the crop correct in the camera so your not wasting pixels..but I would go on an overcast day, or early in the evening or morning and capture light that isnt so harsh.

I like the crop Buddy put on it and I think that he nailed the best approcach with the current photo.

When you go back don't forget to play with perspective as well....maybe try tome wide angle shots showing depth.

Just some ideas..
