Now and then I get messages/comments from younger artists asking for promotion or what have you. Some of them are clearly copy-pasted and I tend to ignore them, but some are more earnest and sincere and for those I decided to type up a chunk of advice.
Treat other artists like peers and interact with them accordingly. Make real, organic connections, not forced ones. Keep practicing and sharing your art. Share things you like. Talk about things you like. Find people with similar goals to yours, who get excited about the same things; help motivate each other. Expand your skillset—learn how to code or craft or do 3D; learn some graphic design and typography. Don’t put yourself down. Have a portfolio online. Use social media to actually socialize like a human being. Work, be patient, and work.
This shit takes years. I’ve been doing all of the above for a decade and I’ve just barely started to go somewhere with this. Even if I slapped your URL up here for all my followers to see, it still wouldn’t get you very much progress. All those things I listed are like planting your roots. Nothing will make you magically grow into a professional artist overnight. It’s something you have to nurture and maintain over the long term.
