Howling mad!

Having got as far as the yellow basecoat yesterday, I have now decided to abandon the Imperial Fists idea for Howling Griffons instead.  They have a red-yellow quartered scheme.  I doubt my sanity at times.

First off, I wonder how many red pots I will need for this?  Secondly, I've never done quartered armour before and I hope my lines are straight enough across the whole squad.  I will also need some transfers, which I think I can get from Bitbox.

So far I have done a shade and a layer on the basecoat on the yellow quarters.
