Callandor

My rendition of Callandor, the crystal "sword" Rand finds in the Heart of the Stone of Tear, in Robert Jordan's "The Dragon Reborn", Book 3 of the Wheel of Time saga.

This object is just one element in a piece I'm submitting for Robert Jordan's Wheel of Time Calendar this year, you can see the scene I'll be using this sword in here :

Any critiques or opinions or scorn would be much appreciated! Thanks for looking.
