Entelechy

The darkness of the piece works well for the colours that glow from the jewels. The way the dark tones are blue with hints of red in the far background give it a much more appealing nature than if the work had just black and grey shadows and brighter highlights.

Although, the overall work has an unnatural depth of field. I know it isn't a photographic work, but your style in this work seems to recreate the depth a photograph would have in this instance; that is, have a foreground, midground and background. In an actual photograph, the midground would be in focus whereas the fore and backgrounds would be blurred.
However, areas of this work are kind of confusing where quite a few portions drift in and out of focus, with areas in the foreground seemingly focused, some in the middle in and out of focus and areas of the background in focus as well. The glow on the foreground right gem seems to blur the metal vine that encases it.
This overall effect appears quite strange and I don't believe it to be effective for the piece.

I do like the vague shadows blow the top level, where underneath the vines there's another layer. It does give the user a little more scene as if we were in some sort of strange tree on a branch looking down.

The overall work is beautiful and differs from your usual style. Quite beautiful! <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile) - "/>
