Cryx: Nightwretch and dock basing

In a couple recent posts, (1, 2) I was testing out some ideas for a paint scheme and a basing scheme for my upcoming Cryx army. The first model I've painted up as a sort of test for the ideas is the Nightwretch. Most everything turned out the way I wanted it to so I'm liking the way it's looking and I think I can do a lot with the dock basing for future models.

Cryx Paint Scheme: Rusted Armor

Been thinking for awhile on what kind of paint scheme I want to paint my cryx army in. I still haven't settle on everything but I've known for awhile that I wanted to do a beat up rusty cryx. So, I've never done a chipped paint/rusty effect before and I always like to practice new techniques on test models. So this is the color scheme and my first attempt for how I'm looking at painting my jack's armor. Disregard the dragon head bits, just the center bluish/gray part. Thoughts?
