Draw Upon Drawing when Developing Projects

See this crude drawing? I just grabbed an index card and a marker and drew this. It's a mockup for a scenario that could be the basis for a novel chapter. Took me 30 seconds. Now, why would I inflict my lack of art on you all? I mean, look at that man's head! Is that even a head? And the flying saucer -- looks more like a sinking speed boat. Please.

Crude though my drawing may be, you do get a very clear sense of what the dramatic tension is all about in my fictional fictional book.
