From the update:
Ok so decided these are pretty easy to sculpt so changed one into a egg base and set a couple figures on it for scale as well. I think it's a fun base for a hero alien and I'll work toward doing more bases later but for now get you the terrain bit of an egg freestanding. The metal figure is a space pirate in our TFM store I used for scale, 28mm. Let me know how you like the styles here and this might just become a free base gift for a leader later in the kickstarter.
