I'm 40 subs away from 100! One of my challenges is growing an engaging audience. Sometimes threads like these help, sometimes I'll gain subs from nowhere, but most of the time nothing happens. Also only a small percentage of my audience leaves comments, likes, and views, so it's hard to tell whether anyone actually likes my work or subscribed and forgot, or plan on binging it later. I know you're supposed to advertise on social media, but I don't have much of an audience there either. Plus, I'd lose a follower every time I'd advertise my comic on Instagram, no joke.
Another challenge is time. It's hard trying to maintain a buffer that quickly diminishes. I'd prefer to be at least one chapter ahead, but unfortunately I'm behind this time. This lead to the last chapter being updated at a slower pace than the previous. I don't want to keep people waiting too long because they'll get bored, move on, and possibly forget, especially if you're not big.
