Linked Here is my Etsy shop for you to take a look, maybe give some feedback on what you would or wouldn’t do differently. I opened my shop around a month ago and have made around 3 sales, most of my sales in person are just close family members.
I buy art for my home often, so Yeah, hate to say it but if I spent a half year painting every day, I could paint these eventually. I don’t want to buy something I look at and think “I could do that if I gave it a couple months effort.” When I look for art I go for something that stands out in an elegant way, and/or a complex way. I’d try mixed media or even impasto. Perhaps take classes on other techniques and shop around for what could be your “thing” that makes your art unique. These pictures look like they’re painted from other pictures basically, even if that’s not true.
Something I haven’t seen is paint mixed with embroidery for instance.
