WHAT DRIVES THEM TO DRIVE AWAY?

Are they driving away from that bomb? Is that what that object is? I'm kinda confused here. Like the drawing, though, except for the ambiguous object.

haha...you're right. A polluted earth is like a bomb.

Okay, then. Well, the earth should look more like, well, the earth, with continents visible. And, perhaps, adjust the illustration so it more clearly shows them speeding away. As it is now, it looks kind of like they're leaving one of their own behind.

So long and thanks for all the fish.

yeah I thought of hitch hiker's guide to the galaxt too when I realized that it wasn't a bomb.
maybe there should be some color? (so it's clear that that's the earth)

yeah, andorra's right Douglas Adams
-so long and thanks for all the fish:)

I really dig your drawing style, I just hope the idea behind it will be something that appeals to me next time. Can't wait to keep an eye on your future works.

dig the concept just not a shirt i'd buy personally.. 5 though!
