Excellent staging and concept. A little hard edge... my thoughts, but I would imagine it very difficult to not have that effect with the cut edges of the glass. Great shot 8
I like your idea. Some areas on the glass look a little...odd. Specifically the bottom left area of the glass between the purple and darker purple/blue and the right hand side of the glass along the red edge.
Nice idea, been done a few times in this challenge but thats nothing to lose marks over.. I am a sucker for a square crop. Sharpess is good, lighting is strong. good 7
