@JGoldman10,
Do you have an agent yet? Maybe an agent can spnd som time with you and explain what codes are involved in cartoon novels, especially when you announce that theyre for kids.
I did commercial and political cartooning in my past and I still do free-lancing.
\It sounds like you are fixated on a very narrow focus of topics. If you want to make it more interesting an fun (which often translates to success), you should expand your horizons to kep many points of view and many livelihoods. I did cartooning for a rural farm news and I used to get all kinds of hate mail and love mail. BOTH WERE LOVED by the editors because they derive from the same point SOMEBODY IS READING.
I used my rural cartooning based on Mark Twain when he edited a western agricultural news and he purposely fucked up his instructions to his readership.
Like picking pumpkins from trees.
People wrote all kinds of nasty letters but readership soared.
I dont think you really want any advice fom experience I think youre just looking for people to underpin your POV and thus bolster your ego.
Good Luck though. I can tell you that cartooning is like anything else, highly competitive and often luck plays with you or against you. I hired an agent quite late in the game but he's been worth her contractual fees.
