Nice. I like the sort of "layers" or levels of roundness - the dome, the arches, the balls, the crescents. Good cropping and composition to draw that out. Lighting is ok, probably better than most times of day - the shadows are there, but not too dominant. Focus is good, sharpness could maybe be a little better, but it's OK. Overall a nice shot, one of my favorites so far in this challenge.
with the theme "Round" in mind, maybe if you cropped most of the bottom half of the picture and left just the small domes and large dome, then I feel it would have more impact.
This is a very fun architectural shot. The lines and curves and highlights and shadows all come together to create a balanced image. Nice job!
