I always enjoy trying different techniques on flower paintings. I haven't found there is just one way to paint them... yet.
This one I painted the flower first building up to the light. Then even though the background was toned, I painted the background darker around then flowers.
The second one was a different approach. I toned the dark background first, then painted the lightest lights of the flowers.
Either way I had an enjoyable time playing with peonies.
