Not sure if I should ask this question, but
How did you get so famous and avaliable to live from your art?? It was because an early algorithm miracle or it was somenthing else?
All artists know that dedicating yourself to this requires a lot of effort and sacrifice during years, and that no matter how good you are at drawing, you also need certain knowledge in addition to drawing skills.
Any tips of what other non art skills are esentials for living from art?
This is actually really hard to answer, because even if I listed every single thing I ever did, it doesn't guarantee it would work for another person.
The online landscape has also changed so much since I got started on it, and things are incredibly rough for all creatives right now. My expertise also revolves around merchandise rather than freelance, so I can't speak to making it strictly as an illustrator or artist-for-hire. But here are some bullet points on things you really need to know/do to be a sole proprietor of an artist shop:
Strong work ethic. You have to manage yourself and that means getting work done, staying on task, and not goofing off. This is harder than it sounds.
Social media skills. Be productive and active online. You not only have to share a lot of art, you have to reply to comments, have convos, look at and comment on other art - not post and ghost. Learn to repost often and take advantage of viral trends or events/holidays. Curate your account well - don't shitpost, don't complain/rant often and limit reposts to content related to your own.
Website design. Use templates if you have to, but make sure people can easily navigate your site and get to what they want as fast as possible or they'll bounce. Make sure it works on mobile too.
Photography. If you're making merch you need good photos of it and hiring photographers is expensive. Learn lighting, composition and photo editing. Good photos can make the difference between a sale and a bounce.
Logistics. If you're selling merch you have to learn the ins and outs of shipping. This means knowing the best methods, providing accurate rates, troubleshooting common issues and learning how to pack something so it's secure and also as light as possible to keep rates low. Ship orders fast, people don't like to wait. You can also hire a fulfillment company but that can be expensive.
Did I mention graphic design? You have to learn to create and set up files for print/production, as well as make appealing packaging, and you also need to learn how to create eye-catching ads, site banners, calls to action and more.
Research & Design. Good and unique products are more than just slapping a picture on an item. You have to design specifically for the item and also seek out reputable manufacturers with quality merchandise (this has gotten extremely difficult in the last decade or so due to capitalism's race to the bottom).
Marketing. People are pretty sick of ads so you have to learn to make ad posts that aren't annoying and people might share. Learn how to write good newsletters. You also have to advertise a lot more often than you really want to.
Customer service. This is another hard one. Reply to emails within 24 hours. Learn to be polite and not lash back at angry customers, and understand that sometimes you're going to eat the cost of something to make things right (like replacing lost, uninsured packages). Accept it and write it off as a loss on your taxes.
Speaking of taxes, bookkeeping. You have to be diligent and accurate, and you will pay more as a sole proprietor. Find a good CPA, keep meticulous records, learn what you can deduct, and get set up to pay quarterly income taxes. Put (a lot of) money aside specifically for paying taxes. Don't forget your business licenses, too.
Conventions/tabling. Sometimes online isn't enough and you have to make in-person appearances. This is a whole extra skill/knowledge set that involves things like travel, merch displays and temp business licenses that I can't also get into.
Video creation/editing?? TikTok is big but I personally can't get into it. Can't help here even though I know it's important these days.
Overall you're looking at wearing a lot of hats and doing a lot of jobs that most businesses are able to hire multiple people to take care of. You have to be focused, productive and work really, really hard. You have to be confident and make important decisions all the time. You also have to be able to accept failure and try again, as not everything works out and that's okay.
I personally enjoy the core tasks (product creation, website design, photography, etc.) and I'm also a homebody with no social life, so I have lots of time to dedicate to my craft. But it's definitely a hard row to hoe. I work very hard at it.
I hope this helps shed some light on the workings of this kind of career. It's not just algorithm luck, it's a lot of knowledge, multitasking and hard work.
