Very nice, especially the lights. Do you have a ratio of skirmishers to hoplites in the rules?
I've based my figs for this period on large single bases too, though not as big as these. I think its an excellent idea, after all we spend so much time painting figs that we do them a disservice by squeezing them onto a little base with a green clump and a rock or two. I use Minibitz 6mm dice and frames to record casualties, tucked behind a figures leg, they're almost invisible on the table top.
