For my taste also, that is way too much white, but it should make a fine quilt. Do check it with batting, which will change how things look. Sometimes when I am concerned about a darker fabric showing through, I clip the seam allowance close to the cross seam and turn it back the other way. I learned this in tailoring. The top as you made it is a very traditional one. BTW, I agree about the quilting. I would do it in blue or mixed blues, but what matters is what your friend wants.
