Interesting, and nice macro capure, good focus, DOF, lighting, and composition. If I have a nit, it's the mark on the floor, which is a scratch of a nit. Nicely done and effective.
In my opinion, this is the best shot out of the whole lot. No one else used the same idea you have so creavity and innovation is very well used in this. Plus it has that eye catching element. The shot was taken in a pretty decent angle. I took a point off because the plant looks desolated, and the elephant decoration looks too big in proportion to the picture. Excellent work though!
8 - Like this and good set up. Criticism; not much, maybe some type of small lighting for added effect would have made this even better. Maybe a slight crop change, especially to eliminate that whiteish mark fore right.
