Comic book cover parody

As a kid, I always wanted to be a comic book artist. My high school teacher, Margaret Stein, steered me into the commercial and fine arts fields. I frequently create comic book cover parodies while practicing and learning on the computer, I've done over 200 of these just for fun. I have had some exhibitions of these prints in galleries and local museums. I may eventually try to publish these as a book. I've approached publishers but no response so far.
