This image does a nice job of meeting the challenge of multiple light sources. Quite evident, which helps. As for the image itself, it's "ok". For me personally the subject matter lacks interest. JMO of course. I do wish you luck in the challenge.
The artist seems to be very talented indeed. The photographer did a very good job too. I like this because it's different, the colours are beautiful (and it meets the challenge ;-)
There's a lot to look at ;) I think a scaled down version of your idea with someting more specific in mind would have offered a better composition. You have an excellent "vocabulary" for light sources, but (IMHO) I wouldn't use them all at once.
