RIFT CaC: Colossus of Death

This is my work on a special Colossus Boss for the MMORPG game RIFT. I would, if anyone won't mind, express my thoughts and ideas on this piece.

First of all, I have knowledge of this game and I've explored (or rather have been exploring) the Plane of Death for quite some time now, and seeing it's creatures have led me to make something that are able to help them conquer. Something that could harvest souls from other planes of Telara...something terrifying...and hopefully it may be an asset to lord Regulos himself. I have also seen a strategy on how to defeat it myself.

As for the design, here it is:
This creature is made from the souls of the fallen that are harvested by Regulos' warriors and are turned into slaves to form the life of the Colossus. The structure are of bones from equally dark creatures. Since the souls are corrupted by the influence of the Plane of Death, they induce the same violet glow as the rift from which they are spawned.

I wanted it to feel like it was part of RIFT, and didn't want it to feel like another game.

The Death Colossus stands before thee, and I hope that I make it in. Thank you.
