Kevin, your original looks real good. All I did was to convert the owl into a silhouette and leave the eyes shining.
I saw a painter named Jerry Yarnell on a TV show paint an owl on a limb silhouetted on a yellow/golden full moon. The painting is called
The Watchful Eye.

Scroll down to near the bottom of the page to see the painting. The video link is just for the first part of a multy part series of the painting and does not show the owl.
