I really, really like the color purple in your square. What I'm having a problem with is the 'busy-ness' of the pattern - the circles are too big for the rest of the fabrics. I think it's too busy and detracts from the beauty of the trees. Do you have another fabric that color, less busy, that you could use? Maybe a blender or marbled purple? JMHO. I like your block. Don't get rid of the color purple - just that particular fabric. It makes your block pop.
