Jakar: alas, these are the only ones I painted! With a 10-month-old baby in the house, painting time and energy are severely limited. A horde would have been so awesome! These are a gift, so maybe I'll do some more later and send them to the giftee for his collection.
The bases are covered in a mixture of clear acrylic gel (the stuff I use as water, actually) and beach sand. A sort of poor man's texture medium. And that foamy foliage from Woodland scenics.
