One thing I learned in all these decades of being an artist is, if you wanna get noticed on social media...
NEVER. STOP. POSTING. ART.
Even if you don't get thousands of likes on your first post like some people, just keep drawing and posting. You'll only improve, and little by little, people will notice, and those who are actually into your art will follow you, and your influence will spread.
There will be times when you will feel discouraged, but if you power through, you WILL make it someday.
Just hang in there.
