@thousandwrecks - really nice work and neat to see your thought process.
I was recently looking at Alphonse Mucha's work because of the recent Three Point Perspective episode where Lee White mentions his work. Your work reminded me of a more modern take on his style. Perhaps you could do a more modern ornament around the framed circle using the swans?
Here is an image search of Mucha's work so maybe you can see what I'm talking about: https://www.google.com/search?q=alphonse+mucha&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj3m9zPhLXjAhVN7J4KHZU0DLwQ_AUIESgC&biw=1920&bih=969#imgrc=hNoGYxAawe9STM:
