Attempt at Crowd Control

Here's an excerpt from a comic strip I drew as a tribute to a web design teacher; mostly it's about him murdering the class one by one. I'm posting this particular panel because I think it's one of the most interesting... and one of the most complex things I've done in recent times. Drawing crowds has never been my specialty(in fact I stumble with more than 3 or 4 characters in a frame) and here not only I had to show a small group of fellow students, they were supposed to run away horrified in all directions. I guess it turned out nicely... at least you can tell what's what.
