Looking good, however i do think the crystals could use some more angular shaping, they don't look very crystal like to me, they look like a carved piece of wood, can sorta see multiple curved carves along the length of the crystal which isn't a natural crystal look ;)
moar glow!!! Ramp up the emissive and contrast on those crystals to match the concept. nice sculpt on the metal components though. Especially the little hand in the middle.
