Necron C’Tan Shard / Transcendent C’Tan

I was lucky enough to get a Necron Obelisk / Tesseract Vault for Christmas and have decided to build it as an Obelisk for that lovely Gravity Pulse each turn to ground flyers... there is always next year for a Tesseract Vault! So as I build and paint the big bit, the leftovers give enough pieces for a C'Tan Shard or as Alex (From the Fang) points out, a Transcendent C'Tan!
I decided to build it with a metal base piece so imply it is still under the control of a Necron Overlord, and from a black base I built up the colours from Scab Red through to Yellow. I know fire glows the brightest from the centre, but I'll leave that to the next year's Shard...
