Read only the comic, didn't know much about the deceased. But it sounds like he contributed much to this project. He must have had some serious talent.
It also seems like he was a major part of this. Do you think letting this die would make him happy? Continuing this work seems, in my opinion, like more of an ode to him than a single page. And once the works are published, a many-page explanation of him and his deeds would make him more well-known.
Ooooh! We live in the Highlands with our kilts in the wind! We're the Tartan Army, come join us, my friend! We look so dandy, jolly, and bloody right! We wear tartan because of our Tartan Pride!
