First of all, that really is a fantastic piece of pure surreal art!
I love the symmetry that was created with the reflections, especially the middle part, quite a tricky 'food' for the brains to recognize that. Really brilliantly done! I think the lightening is interesting, also is the composition, when observed from the whole view.
What I adore by abstract art is that it has so many ways and possibilities of interpretation, which is exactly why I could stare at this work for a long time and every time I'd that, I would probably find hundreds and hundreds ways of interpretations for it. As said before, this is pure abstractedness.
