Hi Nathan,
Broken: I really like this. I echo others comments that it is a bit tight on the left and bottom. A great mono shot though and a good interpretation.
Entertain: This really portrays entertain for me. Perfect
Spiral: Another cracking shot. It works well the have the whole spiral and the plane in the frame too.
Silhouette: Good shot from an interesting angle but isn't really enough of a silhouette for me.
Animal: Good macro shot. Sharp and well composed.
Medicine: I'm with you on this one - it's been a bad year it seems. Good fit to the theme and having it in mono works well.
Proverb: Not heard that one. I really like the detail in the embers. Excellent stuff
Pale: Good play on words and capturing the water drop is fantastic but I would like to see more detail in the pail. Re the crop or edit to make it more interesting, you could try mirroring the image to have the pail on the right hand side maybe?
