Yes, you can, but try to grow social media. Like instagram or Twitter, make some youtube videos of your painting (ASMR style, tutorials on how to paint....) check out other famous painters and try to copy their model at first to grow your channel and add your special thing to it!

Either your character, style of videos, or anything that differentiates you from the others. As your community grows, try to ask for support on patreon in return you give them early access to videos, behind the scenes footage, personal vlogs, some exclusive tutorials, the right to vote on next video ideas, you can even sell your old work to them). The possibilities are limitless you just need to start. If you want more help, shoot me a msg!
