You already made it red before I could suggest Wazdakka Red or something a bit darker for the Kell Hounds.
Good iterating, sir! That is one of the tricky parts of the hobby. Next week I'll post a star of mechs that I probably should have iterated more on....but didn't in my rush to finish before the Mercs KS shipped.
Sadly, My shipment hasn't shipped, and I'm done with the Star. Oh well, good work!
