Recycling Bad Paintings

I'm experimenting with recycling some of my older bad oil paintings which are on hardboard into pastel surfaces. I decided to try covering up the paintings with my homemade pastel grit recipe. I had enough of my clear recipe and the black recipe to coat two boards with two layers.

I covered the lower left with the black and the right hand panel with the clear.

Here is the clear panel (upside down), along side a thumbnail. The thumbnail is older and I really don't remember what the reference was. So since I was experimenting, I thought this would be a good beginning for this pastel painting.

 Work in progress:

 Here is the palette I used:

And the final painting - I'm not sure I liked the feeling of this recipe on this hard surface. Soon, I will try the black panel for another painting and will post it here then.
