I rendered these crystals in cycles, and I’m pretty happy with the result, but it seems like something is missing, ideas for improvements anybody?
Maybe make a cave full of them instead of just a small group?
make the superman bunker or whatever its called. where all the crystals are.
make more of them and give a nice dark background to it showing a mysterious effect 
cracks in the crystal, inclusions perhaps, and very, very subtle reflections or slightly rough surface.
thanks! i’ll try those and see if it helps
Maybe some transparency…
Most crystals have it.
They look very dense.
