You cant sell your own art. But if its in the gallery and people like it theyll buy it without your say. the only way they wont buy it is if its declared your favorite.
there is also a scale.
Itll say what it is rated as
Trash-little money
Respected-medium money
Magnum opis-lotta money
I see - so how do you not get trash then? What sort of stuff should I paint?
