Well, the sad truth is...If you waited around for viewers to participate in your comic, well, your comic might literally never get made. Now, I don't know how much engagement you get from your viewers--if you already have enough then cool, but if you don't already have enough engagement, then, does that mean this segment of the main comic might never get finished? Is there a backup scenario in case of this circumstance?
I don't want to uninspire you or anything. I've just done a "Ask my fictional characters anything!" twice to absolutely no response so I'm like okay, cool, I'm just here to do my thing, then.
