Cheers @bucho! And thank you for the resteem! =)
Yes, first time around it was really hard to let my painting go. But I soon realised it is a rather cathartic process, very freeing. Sometimes you hear back again, when the owners randomly send you a message and photo of how happy they are. Its nice to know that something you've created is constant part in someone's life.
I guess for you as a writer the satisfaction is to see your work replicated.
