'Chablis Plumeria' 16x20"

I was very excited when a Facebook friend posted a photo of a single Chablis plumeria.  It has a very deep yellow/orange center with a pale pink around the edges.  Unlike my previous painting of the white Singapore plumerias, this one will have very large blossoms and a very loose background. I am using 300# Arches watercolor paper which is whiter than in this photo. I started with the shadows first.
