Do I, or don't I?

I've recently been developing an idea and whilst this idea hasn't yet materialised, the process (experimenting, particularly with colour) has produced some new pieces I feel are worth sharing.

Working with pastels isn't easy, the reason for this is because its difficult to work colours into and on top of each other. Every now and then, something unexpected happens and to my surprise it works!

Now, in the past I'd give my work away to those who want it. This piece is currently on my bedroom wall along with a few others and I know someone who really wants it. DO I - give it away? Or DO I - keep it for my collection?

As the years go by I start to think of just how many pieces I've given away. Is it time to start saving these pieces?
