I always enjoyed Rackham miniatures back in the day. It was sad to see them go, but a whole host of sculptors came out of that training ground... to do do much of the ground breaking things I see so often today.
I have some photos of the base by itself, just like the Frost Paladin and the ice flow base.
Like the ice base, this was created with sculpey clay. I put some of the Hangar 18 foliage on there to match the vines which were sculpted into it.
