Positives: The crop is good and even and the archways in the background are aligned nicely. Nice textures, with the brick and stone walkways. Meets the challenge well.
Possible Improvements: Lighting is a bot harsh, as folks mentioned below, the background area and fountain is a bit overexposed. Since you are using natural light, I would suggest either taking the photo earlier in the morning or later in the afternoon. You could also try using a neutral density filter or polarizer to help with this. Colors are also just a bit dull, which I think a polarizer might help correct.
Overall, this is interesting photo that with just a little correction on the exposure, would be a great photo.
I think this would look nice with a diffuser filter or the fountain doing something a little nicer (if it changes sprout styles). I like the composition
