Yeah, you just need to expose yourself and your story/promote more, if you are willing to, that is.
Stay hopeful, keep on writing/drawing, don't spam, and let time run its course. You'll get your loyal readers in time.
(for the record, I'm only a year and a half into Tapas and just hit 70 subs, half of them loyal readers, I wager. Most others get over 200 from sub4sub, so there's always that if you like numbers XD)
Good luck, friend. I'll try to take a look if I have time.
