Beautiful paintwork.
With most all of my markers lately, I've been modeling the base to accept really small dice, like 4-5 mm dice, very tiny. I bought like a lot of 50 of them from a specialty store for really cheap. So now I have a counter for rep'ing multiple fatigues or wounds or whatever.
Or you could even do like my buddy does with his where he has like skewer sticking up off the base that he drops skull beads on to represent wounds taken.
