1. I don't find your strips humorous. It isn't because I'm being a jerk, but rather...it isn't funny.
2. The idea that it's an ongoing series of stories is nice, but that's about all that's nice.
3. Nothing grabs the person who reads your strips, so there's nothing present to make the reader come back.
4. Seems you use a good vocab in your strip, but it could also use humor.

Overall: Predictable jokes, no real humor, and nothing that's truly enticing. From 1 to 10, I rate it 2. If most of the stuff is inside joke humor between you and your sim group, how are others supposed to understand?
