Shorter comics! I think that's honestly the biggest determining factor I have in my favor. A lot of writers looking for artists go the route of reaching hundreds of chapters without trying anything smaller first or considering how much a commitment that is for the artist especially if they're not getting paid. I initially came here intending to make that mistake before I learned about the community and how these collaborations work. And I learned my lesson real fast lol If you're gonna make something and ask for help for free, at least make it somewhat short.
Of course, it doesn't hurt to be a regular, to have an appealing premise, or to have reasonable amount of your own work already done, but still. Shorter stories are your ticket here if you don't have any money for collabs
