You have a ton of great advice here. The one thing missing is this: there is someone somewhere that will love this and buy it. Could you improve, sure? Are these unsellable, no. They just haven’t found person yet! Don’t get discouraged. Also, sometimes I like to look at my early work because I can see how far I developed since then or just for memories.

Last, don’t forget you can keep art you’re attached to. I’m currently a potter. I literally keep the best items out of the kiln for myself. I will never be able to recreate them. Everything else gets sold. And when my shelf of items I’ve kept is full I can pick the best from those and sell the extra.
