Went into my mecha modeling bag o'tricks for some things on this one, particularly with the oil filter I applied over all of the armor parts when I was nearly done. Some of the weathering came out a bit more intense than I wanted, so it needed to be knocked back, and the filter did just that. I'm still not happy with the pauldrons and some other things, but I'm calling this one finished. I think the issue really was the round shapes of most of the armor - I usually do this sort of weathering on Gundam and Zoids kits where there are lots of sharp edges to do chipping on. Here it was kind of hard to figure out what to do.
Anyway, more pics in my gallery if you want to see 'em.
