Hi Cathy. Looks like you hosted quite the tropical sketching gathering!I'm particularly taken by the technique you used in the bottom sketch with the window of color. Beautiful effect!
The only thing missing from the top sketch are the word balloons coming from Sherry: "It would feel good to be naked here." and "That looks like fun. We should do that." Hope to see more of the "out of the box" technique. I think you're onto something with that.
