hi, firstly i would say it loks a little overexposed and the background is too busy with what looks like a building site going on, takes you away from the ampitheatre, I would also say the building in the background is more in focus than the main subject, have a go at cropping the image and play around in photoshop to improve th exposure, but for me its not a keeper. Its your first post, good on you for showing it, keep at it mate.
Cheers
