I tested out GW's new gold paints on the winged skull. I used a base coat of Warplock Bronze, then a good heavy coat of Retributor Armour, and then wash of the technical paint Nihilakh Oxide. I then highlighted with a light dry brush of Liberator Gold. The new golds provide excellent coverage. I am very impressed with these paint, they are definitely worth the extra money!
I added a mixture of Jungle and swamped tufts to the (very grim-dark) ground around the bunker.
I originally painted the outer walls green, then used making tape to cover odd shapes around the bunker wall, and then dry brushed over in grey. this gave me a camo effect when I removed the masking tape. I edge highlighted some of the green to help it stand out a little more.
To finish off the metal I highlighted the edges with Rune Fang Steel. I added it to the gouges and damage as well.
