Yes, it may have had more punch if the courtyard had more light but that would kinda defeat the feel of a little sheltered and hidden courtyard surrounded by buildings which steal the light.
Wow this is interesting. Who would think to put the green stuff between all these cream colored buildings? I like how you've captured the light creeping into this area.
Looks like these plants don't get much winter light, making for a somber theme in the center despite the warm surrounding indoor lights. Also looks like a candidate site to practice HDR approaches (when not required to stick with basic editing).
I like the use of lines from the two buildings. The courtyard seems a bit dark, probably becuase there was such a range of tones in the shot you had to struggle to balance the highlights and shadows. It also appears to be suffering a bit from motion blur or being OOF.
Nice shot that meets the challenge well, the high contrast between the sunlight and the shadows is a little harsh, but there was not a lot you could do about it.
