I've also painted a black rim around all their eyes, which gives them more definition ... as I mentioned to Christian (whose suggestion it was to do so), I hadn't noticed until I started painting the rims that their eyes had previously looked like they were floating slowly off their faces!
I'm quite happy with the results - they've taken on a more "animated" look.
Here are a couple of hammerers with the standard bearer and a pike-frog. The hammerer with the hat is the champion.
And here are all the hammerers!
I hope to post some pictures of these little guys in a proper setting in the next few days, so stay tuned!
