I used white as the base....kept the palate very simple on this  - 2 colors and a simple gesture.

 This was the first attempt of the day.  Started mixing colors off the sheet today, working with the roller more as a brush.  This one below is a continuation of mixing colors.  I started laying in the pink color and worked into and around the central area. 

I think this piece works pretty well, I would like in the future to establish more foreground background relationships.........something to work on in the future.
