Next steps were to mix up some nice pinks with alizarin crimson, some white and blue. Dragging the gray of the pencil around with a bit of turp, helps to put the lines I drew into a bit of gray that I can use for guides and add to the under layer. I also went in with some more whites over the grays and pinks. The owner wanted me to add a collar and a heart shaped tag that wasn't on the original photo either. Happy to comply! More reference needed.
