The marines have kind of a "dirty" look. It's not so much a conscious decision as it was what I ended up with. I hope the shoulderpads + arms/weapon is going to balance the marines out a bit.
And here the two little side projects. I thought that painting Orks would be hard as heck, but not really. It so happens that models with a lot of stuff on them sometimes are easier to paint. The Marines are far more "clean", but that just makes it harder for me. I hope you like these guys, they have 3 more Nob friends primed so I might just finish those three as well, to have myself a little Nob squad to look at me when I paint :)
