these are really GREAT posters. i still think you are the best up here (even better than AA, if you can imagine such a thing is possible. just ask 'em! heh heh!)
however, i'm going to say to you something that i said to jeff kleinsmith about 20 years ago.
"stop doing crazy faces."
back at the time, jeff had been doing one great cool flyer/poster after another, each one better than the last. i kept them and looked at them all at once and realized every single was a crazy face treatment. you have the same situation.
faces are easy. you have that totally conquered. it's time to move on. just do a crazy face every once in a while (you don't want to lose that, ever!) it's time to expand your vision - extend your horizon. branch out.
maybe you might try doing a torso or a whole body or maybe something inanimate next time. a landscape. a machine. a scene from a movie. an abstract design. anything but a wacky crazy zany face.
a number of years ago when i had my show at PS1/MOMA, there was a young gallery guard - turned out she was 18 - who was looking at some of my 45's hanging on the wall. she said - "these things actually make music?" i explained roughly how a record works (needle, little squiggles, amplification, etc.) she was really impressed. she'd never heard of such a thing before. she said her dad had some old records, but she never thought about them before. i pointed out how cool it was to have this chunk of colored plastic that has a song on it forever. a light went on in her eyes. she went back and stared at them for a long time.
