I can see that we joined Steemit around the same time & if your story is anything like mine - your friends/followers from other platforms are not here.
This means starting over to build that following here, why not reach out to other artists, enter into competitions and spend some time in chat. It might feel like a lot of effort but I'm certain that it will improve the performance of your posts.
I hope that you'll stick around and that things will improve for you.
@clevercreator runs a training program that costs $1 that could definitely be of help.
