Slowly but...

So as I continue to somewhat haphazardly apply paint to canvas board, I figured I'd upload a few photos of the latest works. Earlier I posted my first painting a take off on Jasper Johns' targets. This online set has another one. This one is better color wise, it's less pure primary color and I think that helps. Right now I'm playing around with collage, which creates depth far better than I could using just paint. Trompe L'oeil masters don't have much cause for worry.

Suggestions? Titles for the works? How can I make these better? What's missing?
