Heya Cap'n it's good to see you 'round the forums!
Honestly patience and getting to know people. Granted, I don't have a billion subs or anything like that but, I've just been talking with folks and getting to know them. It's been a lot of fun to make threads, participate, and to meet new people. Doing that has really helped me. Plus, I've started asking my followers if there's something they'd like to see. Recently with my novel, my readers wanted to see concept art, so I'm making that. I sort of treat it like a conversation and so far, it's been a fun one.
Maybe do some Summer promotions across your different platforms. There are lots of ways to promote yourself and, sometimes your audience helps you in that, when you communicate with them and let them know how much you appreciate them who knows, maybe they share your work? Just keep crackin' you'll get there! 
HAHA or just go the BL route and send Jay on a smoldering date with Archie. That'll boost your numbers lol.
