...Yes and it's easier than ever.
If people knew how hard I worked to get my mastery, it wouldn’t seem so wonderful at all. - Michelangelo
1. Etsy
If you make physical artwork (knitting, sewing, paintings ect. this is the site for you.
Etsy is the biggest collection of solo artist to ever exist all of which are making money off their own art.
Etsy sells physical works - clothing, pins, sticker's, Framed, teddies ect.
The downside is your incharge of stock and distribution, but this also means more profit for you
2. Printing
This is what I do. Design your artwork then use online services to print it onto clothing.
All you need to do is focus on designing and marketing.

3. Comicon
Set up a booth and sell your artwork here. Bonus points if you can link it to anime/sci-fi/gaming culture.
If this isn't your scene set up a booth anywhere and get selling.
4. AI
AI isn't a robot hell bent on destroying humanity (at least not yet) it's a tool.
Knowing how to use the tool is how you stay ahead of everyone else. And that's all it is, a tool. Knowing how to use it is the key to getting great results.
Simple phrases, describe everything you want to see, knowing the name of your preferred art styles, and most importantly being able to see the art in your head/know good art when you see it.
Amateurs can produce amazing pieces, but if they don't know what makes great art it will always be left in the uncanny valley, or crap.
So how do you become great? Practice. Start mucking about now and before long you'll be better than 99% of all people.
This isn't a money making tip, this is a time saving tip. Times more valuable than money so why wouldn't you use ai?
5. Books
Even if you can't write. Make a picture book. A colour in book. A book of amazing AI artwork. A child's book full of colourful pictures and a simple story.
Then stick it on Amazon. Sell as a kindle book or a physical book. Easy!
6. Freelancer
Upload your art. share your skillset and prices and wait for the work to roll in.
Tons of workers are here programmers, graphic designers, animatiors ect.
