Well here's the base for my razorwing. Plan is to have a decapitated guardsmen (haha Tyler :p) laying on the wrecked reaver jet bike. The blackened corpse was a guardsmen hit by a dark lance (a waste I may add).
I used alot of washes (because their great with metals) including an attempt at verdigris on the bronze sections. I then blended the metals into each other and added some shading.
For the effects, it will be snow all over it. But with a blackened part of rocks next to the guardsmen's corpse.
I will then add a rod going into the razorwing.
