JChaos -- not yet, but I think that they will be. I sent pictures to Pendraken today, and they like the 2 greens. I'm working on a third worm swarm base that will have other battlefield debris, such as an empty breast plate and a standard lying on the ground.
I've also been thinking about re-sculpting the 'plain' base. What if the worms came out of one of the corners, and were radiating out from the exit point? This would be one quarter of a circle, and with 4 bases arranged in a square, it would look like the worms coming out of the ground at one place and going in all directions. Any thoughts?
As for the hounds.... Well, we all can see they need more work.
