it's always better to start with lower prices then slowly work your way up to a price that feels comfortable not only for you, but for your customers. Too low and you won't make enough and could get overworked, too high and no one will want to purchase.

Starting low will also help build more of a name for yourself out there. 10 USD actually sounds like a real nice price to start with. but honestly I think that with your talent and skill, you could probably push it up to 20 - 30 USD over time with almost no change to the amount of people flocking to you, once you start making a good amount of sales. Your art style is a rare type, very unique. That means that those who would want it are searching for it specifically~

So the rarity of the art style matters too? I see now.
For now, I'm going with 15USD for the first batch I'm on, I haven't gone too hard on these designs for now

there is a lot that matters when art is considered. from the style, to the content, to the speed at which it is made, to the quality, to how easy it is to work with the artist, to popularity.

cool to hear!

Thank you
