It's a little bit hard to see, and I think I'd like it better if it had been composed without the little bit of floor at the bottom. Still, a very good idea, decently executed, and I like your choice of subject. 6.
A nice thoughtful choice. You had the right idea isolating a single pattern for your composition. Sadly, this looks very dull and flat, almost as if lit by flash. Also, the corner of the floor at the lower right should have been cropped out.
