Two more rocks

Here are a couple more asteroids, made from lava rocks I found in the back yard (interestingly, I don't actually have any garden or flower bed that contains lava rocks, so I have no idea where these originally came from).

I drybrushed these in the usual way: gray and then a little burnt umber.  In the background are the Stardate: 3000 spaceships I need to get painted.
