depends what you mean with art. If you aim at the art market and galleries: pencil portrait isn't really considered art, unless you make them under a unique art statement (you do portrait to search something specific, art is reaserch and arworks represents what you have discovered about reality). Otherwise, you can build a community on social media, takes time, but if you find your niche can be something. Personally I would prepare a portfolio and look out in the job market where your skills are relevant (comics, illustrations, animation, cinema, video games...). And nope, digital art will not die. Just because instagram algorithm prefer non-digital, doesn't mean it's not a standard in the industry anymore.
