The Seven Poppies Question

This piece has been in the entry area of the Celebration of Fine Art for a week or so.  It's an interesting exercise to put a work out of your daily vision for a while and then come back to it.  I have always loved this piece.  It is so close to a perfect interpretation of what was in my head!  To see it afresh amazed me, and with humility, I say that it is still among the best three pieces I have ever done.

That raises the question of value.  Sure, it has a price tag on it.  But it is a piece that may well remain in my personal collection.  I don't believe in keeping much of my own work.  I think it can be too self-congratulatory and often acts like a kind of glue, sticking you to an idea, an image, an interpretation, when what I want to do is to keep experimenting, move onward, test new ground, push the limits of this humble material, and, of course, the boundaries of my imagination.

So.  Keep it?  Sell it?
