Calvin is the single coolest comicstip character ever made in the last 30 years...
...Unless, of course, you count HOBBES!
Anyway, I REALLY like the background- looks just like a Spaceman Spiff setting. Spiff/Calvin himself looks good too, but the background really stands out.
Yay! Calvin & Hobbes rocks! (Said in the voice they use on Invader Zim when they say everything rocks.) That child has problems....
