I also got an opportunity to paint the Warboss a good friend of mine gave me from his last tournament winnings. I've always wanted a warboss model to represent the "All the Attacks" build with Attack Squig and little else. SEVEN attacks on the charge at Strength 6? Sure! I'd try that!
I haven't decided on a name for him yet, however.
Basecoat with Valspar Labrador Brown
Drybrush with Boltgun/Leadbelcher, heavy on metal areas, light on other areas.
Basecoats. I mainly use Apple Barrel paints.
Dark brown wash, then highlights.
Basing. My orks use a heavy amount reddish brown/wood glue mix dipped in sand, then decorated with stones and a bit of flock. The world is meant to be one where there is a great deal of rain but also a lot of solar activity so it's muddy, but dries quickly.
