I like the way it looks somewhat like a landscape on first look. The lighting is interesting, but results in a harsh contrast that detracts from the subtle patterns, texture and colors of the rock/crystal.
Photograph Information, Technicals & Composition Review
The combined image you mention might have shown more detail, alas with Basic you had to 'redo' and abide by the Rules. Good for you for making that effort. Composition wise it is ok, as mentioned, this composition lends itself to another 'scene'. I can notice, only barely, what appears to be black fabric in the background, but minor. A more refined crop around the patterned areas of the crystal would have been better.
Comments, Score & Placement Review
31/82 is quite good. Your commenters all like your vision.
A good subject choice that a variation in lighting may have showcased even better. Would also have liked to have seen this a little sharper with more texture discernible.
