I think it all depends on the way you feel about the piece. If it excites you then by all means go for the best you can do. If you feel comfortable with it, then leave it the way it is. I know some artists who would not raise their prices and who clearly could get a lot more for their work. They are simply happy with the making of art. Simple as that. They are not interested in the money.
A few others have gone to greater lengths and are asking for more. They are in this (what I consider) an uncomfortable competitive world of artists who are now clamoring for the biggest price value. So who is happiest?
I think it is the one who does what they feel most comfortable doing. I do believe, however, if a piece is absolutely exciting to you, you owe it to God, Mother and American Pie to go for the best, the very best you can do--no matter how long it takes.
