Spray paint... great idea. I tried some metallic spray paint. I really like your use of line and bright vivid colors. The straight lines really bring out the odd shaped rectangles with the contrasting rounded corners. Beautiful drip and I really like the yellow it makes the painting really punch. I would just make sure that the splatter gets incorporated into the overall image in at least one spot. Perhaps put some black line over part so it looks like the splatter comes from inside the painting and is not just on the surface. Otherwise, magnificent piece I only wish I could bring form and color together in such a fascinating way.
