Can you change the color palette of your work to offer multiple options for potential customers? If my artwork were colored, I would change the palette digitally, but if it's B&W like the images above, I would keep it that way(Unless the art was originally done with a digital program, then it would be easier to change the palette).
What kind of products would be a good fit for your art? I believe art prints, shirts, totes, and stickers of my artwork would be a good fit,
How will you promote your work, either before it's finished or after it's on sale? On social media like Instagram, Facebook and my website.
This really was a good experience to explore and make a source of income from. Cat inspires me to try my best, Thank you for all your wisdom :)
