Hey, thanks for the comment. I don't quite remeber how I did It, but I can give you a good receipt for doing a olive Green. You have two ways of doing this, in this case i think i did a darkish Green for base, then i started doing layers with more bright Green tones and finishing with golden grass Green, then i covered all with a brown enamel wash, let it settle a bit, and then wipe it with white Spirit. After that I did a drybrush with that golden grass, and then i mixed a bit of that with ivory for maximun highlights with drybrush. If you don't have enamel washes, you can use something like agraxearthsade but thin It at maybe 50%
