More puzzle fun!

I finally got around to working on the myriad puzzle pieces from my art group. Here are a handful I've completed in the past week or so. The puzzle pieces go back to the owners after I finish my artwork on them. The themes are written on the back of each puzzle piece, as chosen by the various puzzle owners. Can you guess what the themes are based on my work? :)

 The silhouettes, above, are painted using black acrylic.
