How much is my painting worth?

Question

I'm a sixteen year old A-Level student, and someone has asked to buy my piece, so i called him and he wants me to give him an estimate price? i have absolutely no idea how much it's worth, it's on canvas, it's big and it's acrylic- bigger than A2 size..

Answer 1

its only worth what someone would be willing to pay for it. there is no market standard for pricing art.
