Thanks Brent. Unfortunately I didn't manage to follow your advice too well - should have gone a bit lighter with the washes methinks and built it up. But this stuff (AK) is quite fierce...
But overall, not to bad for a first attempt 
Hey matey, nah more likely the way I explain things. I pretty much only line/pin wash and don't wash overall which is maybe how you used the AKs? I think the way they're designed is to go over a clear acrylic gloss coat (Future or similar). All of that gloss/wash/gloss/wash/matt is way too many steps for my taste so my system gets some of that real modeller look but with 10% of the faffing around. I developed my approach though because I don't airbrush, there's painters on here and other gaming forums who do airbrush using the better (proper) system and get results easier.
For me I found that overall washes as well as sinking into recesses, also always darkened things too much, they are a filter in practice as well after all. It's also why I've trended to use much more of a lightened base colour which copes with some shading and darkening and oils for the lining/shading which are much less aggressive in tone, although you can still darken any line in just a couple of seconds if required.
ps when I shade after pin lining it's selective and not over the whole finish, maybe 1/3 to 1/2 of an area gets shaded leaving areas of "clean" paint to provide the contrast. I think I posted some pics back in my thread of a winter Panther that showed some of how I shade.
Seriously good start though, far better than when I started out weathering

cheers
