Achieving that "Playfullness"

During the last crit, I was suggested to look at some of the work of Lee Bontecou, artist born in Providence, Rhode Island, and whose art work is very similar to what we have been doing so far. Her work evokes that "playfullness" that has been talked about previously and that my work is starting to have but needs to be worked a little more. here are some examples of her work, the one all the way in the top right is my intent of playfullness.
