My version of the Lord of Change. Using the airbrush and some speed paints where possible to cover the majority of initial layers.
using the airbrush, spray the tips of the wings and the bottom of the feet using   Luxion Purple  
Using Vallejo lustful purple, paint the wing tips with a fade
Using a 1:1 mix of   Moot Green  and   Phalanx Yellow  highlight the magic details 
Use   Nuln Oil  to carefully fill around the central details on the wings 
Using   Golden Armour  paint the adornments where required and once dried, apply a   Reikland Fleshshade  wash to bring out the edges and darken the gold 
Using   Golden Armour  and   Terradon Turquoise  paint the weapons. After applying the gold, follow up with a   Reikland Fleshshade  to darken it and bring out the details
