I like the composition,the setting and the frame. As for the lighting, a fill-in flash could help the detail/texture of the sculpure which I think is very important.
Great idea. I have some problems with the composition, especially the half-statue on the right and the edge of the pedestal on the left. I'm not sure what you could have done about this. Also, on my monitor, this isn't very sharp. I assume that it's because of the pixel constraints of the site.
