You know what, that looks just like that scene in StarWars Episode II where Obi-wan talks with Yoda and Mace as they sort of walk through the academy. The whole layout just reminds me of it a lot. As far as lighting, I think it could use more, but more contrasting lighting. Brighter lights where it counts, as opposed to 100 lights at a value of 10. Maybe some candles or something to line the pathway would look better. Essentially, its nice, though, so keep going and follow your intuition on what looks right.
