I like panel 3 of 31, but panel 6 is so much cooler....I mean, it has everything: cool sound effects, hyperspace-like lines in the blue sky, stuffed animal dragons set on obeying their (very very very very angry) lord's call....
AND it's the right size and it's pretty!
Edit: Although panel 8 is also awesome, and I'd settle for that as a wallpaper if I had to....
