High up, up in the sky

I am designing flyers for Thought Bubble, or trying to. It's harder to make flyers for something that has people in it than for, say, a comic about a wicked good robot. I try to make the text surrounding the pictures amusing. I figure, what's the harm, eh? What's the harm. I'm not sure any of these four illustrations are any good for my flyer items, I may go a little nuttier, but it's a cobweb clearing exercise and those do no one any harm. Seriously, what's the harm?
