First I want to say that I really enjoyed taking that class and I think it has helped me a lot in my creative process. So I picked the movie Teeth, not because it's my favorite movie but because it's a simple object and I think there's some interesting things to do with that movie.
I started by drawing different lady parts and used the repetition in my poster to make a point.
This is the scanned and vectorized result.
I also had some fun with ink and did some blood splatter and tried to write the title.
