it's pretty darn good for 15 minutes worth of effort.

what was the person in the bottom left supposed to be? just ran out of space?

The right side of the middle guy's head is sorta incomplete still, ear and hair. There's some collision between the two characters there, but that happens on quick doodles. Also, the smoke could be infinitely better. I thought it was lightning bolts for a minute.

very good facial expressions and overall feeling.
