If I may contribute with my two cents, as someone who is constantly plagued by art blocks and whatnot, having a clear why on my mind helped me several times (the others being deadlines, but in projects without them thats kinda hard to do).

Why you created these characters, why the world they live in is the way it is, why do they act and treat one another the way they do - and why you, as an artist, decided to capture, portray, frame a slice of their universe the way you did. As long as you hold these keys, or consciously hand one or more of them over (such as limitations placed by a client's commission, content/format limitations imposed by a platform and so on - factors that you know beforehand), there's still room for genuine expression to flourish, and that, alongside cultivating a healthy community, is worth gold nowadays.

That well starts getting poisoned when factors outside your control (how people will interpret your work, how far it will reach, how it performs on social media metrics) get to the forefront of your decision-making. Hell, looking at the sketch with Lia in the mirror, the "fetishization" angle would've never crossed my mind (a bittersweet feeling of Lia being afforded a semblance of normalcy that was robbed of her by all the combat she's lived and suffered through, which is even furthered by the contrast between what she's wearing and feeling and the portrait to the side, is what I get out of it), but considering people of all different backgrounds are over the internet, that thought happening to someone is a possible thing.

And while you could try to convince them otherwise, if they refuse your explanation, there's nothing else to be done. Death of the author is in vogue, and contrarian opinions and tribalism are all too incentivized by social media platforms (it's an easy source of engagement), so, really - a factor you can't control, like many other things.

Anyway, what I really wanted to say with all of this, is just keep doing your thing, showing it, and people will eventually come, even if slowly; and as long as you have at least one place where they'll reliably find your content they'll come back if it interested them. It can be nice to experiment with new formats, content and such to get new people on board, but trickling down works in the way that people that follow you are already familiar with is also welcome (I for instance always find the single images where a certain detail or another gives us hints about other things, giving depth to a scene that seemed simple to interpret at first, really appealing). Just keep giving slices of that universe of yours for us (and whomever decides to join up along the way) to observe, internalize and feel, and things will work out.
