The description is very good! Just add a note about
"acid-free" and "price tag" to it, and it is perfect. Fine art in all media, can be distorted, even ruined by chemical corruption that happens from something present or absent in the paper, paints, brushes, frame or environment. Even with all such issues carefully minded by the artist at the time of making, most artists simply guarantee their work to cover such possibilities. Such issues can be insidious and can never be totally controlled or prevented, in an imperfect world.
A high price tag does not guarantee quality. A great buy does not need to mean that the quality is less than great.
Still, when an artwork or artist mentions quality supplies or training or experience, it's not fussing, but good business. The intent is to
produce and share a top quality artwork that will last for a very long time, and be a delight to all.
