At some point your going to need to flock the base. I use a mix of Flocking and Ballast from hobby companies and glue it to the base, the glue is watered down PVA glue a.k.a. White glue. Also add bits of real foliage (dried) and or rocks to add more character to the base. And you can also add other bits like bones, weapons, shields, etc from your bits box. This will enhance the look and overall appeal of the finished miniature
