so I've been wanting to make a second guest art feature for my comic Mirror Monster since I've gotten a lot of art to add since I made the last one. is it a good idea for me to post it whenever, or should I wait until the end of the chapter I'm currently working on, which will also be very long? also there's at least one where I don't remember the name of the person who made it. would I have to ask each individual for their consent of me posting their art or should I just wait to see if anyone asks for their art to be taken down?
