The making of a masterpiece

This week's challenge was right in my wheelhouse! I think the Tiger had me in mind!

When I was a science teacher I found a skull on Amazon and knew I just had to have it! (The first day of school I dawned my lab coat and carried Mr. McMasters everywhere. The kids loved it! In the "old days" teachers were given school bells when they retired. I view Mr. McMasters as my school bell. )
Feathers and wildflowers, we have them everywhere in the yard! Ink pots, keys, nuts, thank goodness for my travels!

I set up the scene and thought I'd have it in the bag with one shot...
