Nice one. I like the golden robes (hope thats what you where going for!) and I take it you used metallics on the lightning to get that effect. Add a little white dot to the top of the gems to make them look like they're catching the light. The stone pillar is great very natural looking
I still have one of these to paint some day. His mate got butchered to make Gonzo Lord of Tzeentch:
The flames where done by layering liche purple over black then adding more and more Warlock purple then add fortress grey to highlight.
Normal Flames can be done by going from Black to Red Gore then Mechrite Red, Blood Red, Blazing Orange, Golden Yellow (I then use Vallejo Lemon Yellow) then add more and more white or reverse that if you like realistic flame effects.
Or cold blue flames would also work for Tzeentch.
