Here are some questions i have to know before making any decision:
1-How long does the comic will be/needs to be?
2-Do we both work on the script?
3-Who would draw the comic?
4-Would you credit the authors of the comics? (kinda obvious, but gotta ask anyway)
5-Would you share a link to the person`s comic?
6-What would be the deadline to complete it?
7-How would the final comic work? (the one involving all the OC`s) and how long would it be?
