Add yourself or literally any character you want (unless it isn't appropriate), just don't mess with the things that are already in here unless you feel like it needs improving. (that is if you're even seeing this.)
I did this to pretty much do something a bit more different than my usual projects. The Red Impostor vector is by DavidGamer174. The Yellow Mini-Crewmate vector was made by K_Fall_C. I got the Mira HQ by some sort of add yourself project, can't remember which one though. None of the characters or backgrounds are mine. Ejected v4 is by Rareblin.
