I'm a big fan of this image. I have no technical comments (which is rare: usually I can't shut up) but I love the experimentation with reflective surfaces and deformations in the reflections on the floor. The red, green, and blue lights are a bit stark, but because you use them to emphasize the different relationships between reflective surfaces, it made sense as a design choice. For the same reason, I feel like the image is dark, but that if you lightened it at all then the more detailed reflections would be lost. Lastly, all the objects are realistically rendered, the overall lighting style is good, and I like the focus and delivery of your image.
In short, well done!
