Caution! Falling Rocks (quick layout)

The value range isn't there yet but it give me a good starting point. I like the flow so I'll keep working this up. I have some ideas for more tension and more story to lead to the background. But I wanted to post something up.

2 legged mech designs

I had a hankering for some 2 legged mech designing so, I throw some thumbnails down while trying to keep some fun silhouettes going. I think it went down good, I had fun with it.  I'm at a point where I want to take one farther.  So I thought I'd ask you guys.  What mech would you like to see taken to finish?

Floating City Ideation

Here's a few exploratory shots of the same floating city. 

Covered docking bay

This was inspired by a book called The Moon Is A Harsh Mistress.  It got me thinking, "where's a good place to hide a secrete base to launch your escape to leave the planet?"  In a cave of course. :)
