Cut-out Terri: looks good, with an interesting style. The only thing I don't like about it is the texture (?) you've used on the back part of her hair. It's kind of distracting.
First doodle: some of this is very good. I particularly like the girl in glasses, and the one shouting at you. Very on-model, and funny!
Second doodle: Also funny and well-drawn. I have no negative criticism. The legs are a bit different from on the show, but since you're using your own style, that's OK.
Great work. Made me smile.
It does not matter who I am. What matters is, who will you become?
