Looks like you got some good light for this shot - I like the contrast in the fresca. Is it me or is it slanted a bit towards the top of the frame? Maybe rotate a little counter clockwise to make it even. I like the repitition of patterns in the roof and columns as well.
As interesting as the contrast between the columns and fresco are against the newer construction behind it, it would bring more attention to the fresco by showing just sky in the background. The lighting is great. Nice shadows and details.
