Ork Forgeworld Mega dread WIP

Another project that's on the go. I've got a tutorial coming for the Space Marine commander from Assault on Black Reach, but while I'm waiting for it to render I've worked on this guy a bit.  I have magnetized the arms, but the magnets were a bit small, so I've upped those to ensure it works.  Also working on getting the silver just right... which is hard considering how much surface area there is on this guy.  Anyway, combining some dry brushing with washes and I'll use some weathering powders once I add some extra colours to finish him off.  I'd like to get him a big oval base so he looks in place with the rest of my army.
