Nice collection of 'stones'. Second thing I looked at was your title, which made me look for a face - I thought I saw one, but then the 2 other stones/rocks/crystals/etc threw me. Maybe the face was within one of the 'stones' - I think I saw something there, maybe. I gave up and looked at the image as a whole, within the context of the Challenge. It came across as a fairly static, straight up image of a collection of crystals/etc. The OOF (out of focus) upper left one lessens the overall quality of the image.
Photograph Information, Technicals & Composition Review
If I interpret your Photographer's Comments correctly, it sounds like you put effort into your lighting and setup - which has produced a nice effect, but it slightly softer, with a smoother gradient effect, would enhance the image (and subjects) better in my opinion. The reflections are not strong enough to feature and too subtle and oddly placed that they almost become a distraction, but fairly minor.
Compositionally, it doesn't have strong balance, especially for a horizontal framing.
Comments, Score & Placement Review
You have two especially good and helpful comments that I agree with. 5.21 is quite a good score for this Challenge, and the placement not bad, but given some of the other scores, I might have expected it to be a little higher ranked.
I like the way the colors are showcased against your backdrop/lighting and like the choice of crystals, just wish I could see more detail in them. The upper right one is the most intriguing, to me.
