Hey, looking for some help in pricing up some of my paintings. I paint in acrylics and usually on large canvases and I love having them up in my home, however I've had interest in some. I've only sold up to a2 size watercolours and usually price them on materials used but due to the size, time and effort I just don't know how to price the acrylics. I've attached some pictures of my paintings, they usually take between 1 and 5 months to finish and I just don't want to undersell myself. Thanks!
