Fucked up on my first pattern (too busy for this, may use it elsewhere) but I made a second one that should work better. It was less dense and 1 less color.
I picked up the matte medium yesterday and got around to painting the base coat tonight on the figure's shirt and helmet, and should get my first crack at it tomorrow, if everything goes as planned. I'll post a couple pics if it turns out remotely decent.
Thanks again for the tutorial!
