Scribbled an orc tonight, will do more to it definitely, but wanted to fiddle around with a site i found called DEPTHY, where you can upload or paint a depth mask and it'll, well, you get the picture. :) Try it out, its super fun, its easy to get a proper depth mask from zbrush BPR renders but i think its cooler for 2d stuff (if harder to get right, which this isnt!)
