Well I can easily see them in both If there's a coffee shop that has art up (probably should be similar to yours but idk), you should check out the website to see what they accept. I don't know how they get the paintings, but there's a breakfast/lunch restaurant by my dad's house that has a ton of nice paintings up for sell. Maybe, next time you go to a coffee shop like that, you can casually ask where they get their art from? xD Keep it up! You'll get there!
