Great stuff. I notice you mention unsplash. Did cartoonize a photo? Have you thought of putting them on T Shirts? It's a tough market to crack. I have had shops on Teepublic and Threadless for a few years now. I've sold a few. I notice they often put quirky stuff like your comics on the homepage.
You might not be the least bit interested - but what would you charge to put those sort of cartoons into a childrens book for Amazon? I would do the story. Probably a Max of 10 cartoons . Small kids book. Thought I would ask.
