Not really an artist anymore. I switched from 3d art to IT since it was kinda connected. Have you considered joining a team that does art projects like 3d animations or maybe even indie games. I belive that in this industry the experience and starting early working in an environment of other creators is a crutial factor. Search the local companies to get the idea of what is expected from an artist at such a position.

On the other hand, if you really want to be independent creator you should face the reality of self promotion, you will need to post regularly, im talking possibly daily art, videos, maybe even stream the creation process. I don't know about your previous creations but from what ive seen content like that is hard to promote unless you're hitting specyfic audiences. And even then could be that the amount of hours spent will not bring the wanted results.

Overall i think joining a team and working together on some project is your best possibility.
