They look amazing! I might actually buy the first one! (When I get some money, end of the week ) Different people like different things, the best way to get some prints sold is advertising.
You can, if you have enough, pay for Adcast on here, which works quite well. And then you can also spread by word of mouth. Friends, family friends, friends of friends, your milkman....anyone, let them know about your prints. If they like them, offer to buy them yourself off here, using your artist's discount, and then sell them it for maybe a fiver less than if they bought it off here. That way, it's much more personal, they get it cheaper, and you get more profit.
Just ask different people you know if they would be happy having these on their walls, if they say yes, well done! I would definately like that first one on my walls
how do i know if there good enough to sell?
