How Do i paint Charcadons?

[Solar_Pattern]

So ive always loved the background of the Charcadons (apologies i know i spelt their name wrong) with their gritty nature and their shark like attitude. So i was wondering how i would paint them? I already have an idea about how i would but i have my doubts.

 

(I am a amateur so dont expect class A painting)

 

Undercoat: Chaos Black spray

Basecoat: Codex Grey (using spray gun)

Gun Metals: I dont know if to leave them black or paint them boltgun metal

Detail Metals (shoulder studs, talismans ect): Bronze.

Eye Lenses: Black

Face Detail: Skull white

Wash: Devlin Mud (in the recesses)

 

 

Any thoughts welcome.
