The hull on the right has some Earth Brown weathering powder. I use isopropal alcohol and run along the edges, which helps them 'pop' a bit. The alcohol turns the powders into kind of a watercolor paint almost, it also helps fix it so it doesn't rub off. You always need to fix these powders with a dull coat for models you intend on playing with/handling alot. Otherwise you'll lose a LOT of your hard work and get fingerprints.
A close up, the 'powdered' one is on the left this time. Still more weathering to come. I've laid in the basic colors on some of the stowage and the fleshy,gribbly corrupted parts.
ADDENDUM: Here's a shot of the whole thing after drying overnight. More washes + more touch up ahead.
Off to pick up the Eldar Codex tomorrow (I hope)...for the wife. Yeah, because she has an eldar army she doesn't use. OH...who am I kidding, I've always wanted to do a small Eldar army. Damn you Games Workshop and your allies rules, for making it so easy to rationalize buying more minis! *shakes fist*
That's all for now. Hopefully, I'll have more to post mid week.
