I really like the relationships among the four painting in each of the two sets of paintings. Are you going to put the four paintings (in each set) in one frame or frame each of the four separately? With the four in one frame, you get to see the artist at work, making changes and trying new colors, etc. I don't remember the sizes of the individual paintings. I guess I'm thinking of the kind of things Robert Burridge does with coffee cups, etc.
not sure about framing these but I do like them all together.
