Sorry, guys - my brother abducted me for the weekend, haha- so until Monday, any and all productivity has been disallowed.
But I'll certainly do some paper sketching until then, between Call-of-Duty and watching movies.
I was thinking about a storm-drain environment as well.... Still unsure.
As I said, come Monday, I'll post some more sketches, or a blockout, depending on how far I get conceptually.
So sorry for the delay!
