The image is a nice study in tones but, imo, could use some work. The engravings above the columns on the far wall (the central part of the image) look washed out as do the brick tops on what appears to be reflecting ponds. The plants on the left also look a little light on the upper parts, where they catch the sun directly. There is a lot of the walkway in the foreground walkway. It is kind of interesting for the textures and the need for cleaning, but, were it mine, I’d crop it a bit, maybe about 1/3rd or so.
The eye goes round and round looking for something but i can't find a place to rest and say, “This is cool!” A person or resting pet or even a bird would add greatly.
