I think if you replaced the blocks with the bright white in them you might be happier with the overall look--the white is just too much contrast with no organized pattern. The suggestion of sashing, perhaps solid red or green would help tone it down a little too. But I agree you should finish it, even it is used as a utility quilt in the car. But we all have those quilts that looked better in our minds while planning them, and the actual delivery just didn't measure up. Chalk it up to practice and learning!
