Excellent!!! I am fully intrigued by the whole shot. On one hand it is contemplative with nice shadows and highlights. On the other hand it could be a sci fi scene. The part where the characters get absorbed out of their shoes into the 9th Dimension. I also have to add that the hot spot for me is a key element.
The only suggestion I would have, is maybe put a level on the camera. At second glance it seems close, but something is off.
