Here it is after adding some shadows, and removing some of the pastel on the leaves so the underpainting can shine through, and a bit of other tweaking. The photo isn't showing the brighter tones, the reds, yellows and oranges are much brighter than is being shown here - at least on my monitor, anyway. I am fairly pleased with it, and will put it away for a bit, then look at it again to see if it is worth selling.
I have some pastel portrait commissions waiting to be started. I think I will try this technique with them!
