I think there were a couple people here like @punkarsenic and @amortelito who made some fantastic points.
My first major comic project was Between Hay and Grass.
BHaG is an -extremely- long form comic, where I was BRUTAL about taking my time. In a printed graphic novel, the pacing in this comic would have been normal, but in a webcomic, there would be nothing exciting happening for weeks and weeks at a time -- readers simply did not have the patience to keep up with it.
Reading something like this in a single goal may have held the attention of a reader, but most of the conclusions of these episodes are not even jokes, and most of the time, nothing important plot-wise happens. I was too fastidious about developing things slowly and carefully that no one stayed interested. Likes dropped from 235 on the first page to 9 on the last page, which was a huge bummer. I still like it, though, and I may still come back to it!
I'm working mainly on Mal de Ojo now, on and off with my husband.
The pace is faster and my art skills have improved. I have ALMOST the same amount of subscribers in a little over a year then I did of approximately 3 years of working on BHaG, which had a head start because it was in Staff Picks. MDO's stats have been less stagnant, although viewer interest DOES tend to drop off the longer a series goes on, the more dialogue-heavy scenes drag on without satisfying episode conclusions, etc.
My best bet would be to say this: take the advertising advice that everyone else has given you, and try picking up the pace and ensuring that each episode has a "punch!" You're still super young and you're doing great!
