Caran D'ache Underpainting Only

Here is just the under painting of Caran D'
Ache watercolor crayons. It was done on a piece of Wallis that was already toned red ( A bit redundant) I think the under painting would work best on the white Wallis paper or the Buff U-Art paper. But I had this piece already cut to size and wanted to dive right in and not waste time cutting more paper. The size for all these small paintings measures 6x6 inches.
It is amazing what you can do with a small set of these watercolor crayons. I have done a few others and like them even without going over them with pastel.
