I've finished the triarii and hastati/principes for Phil's prize. Just velites and a couple of generals to go. And of course the basing. I must say I felt a small buzz of pleasure seeing them all together. They really do look like part of an army, which is of course the whole point with 6mm.
I think I will also do a little highlighting of spear points etc, just to give some contrast to the darkening effect of the varnish. I think I'll be going with raw umber as a base colour, with some lighter highlights.
