This quilt feels not so much 'scrappy' to me a "country" or "homespun" or 'cabin-y'. The colors "can be" very masculine. I think tartan hit it pretty close when she made the suggestion to consider other than white for your plain squares....I believe that is what is hindering your "it's perfect" impression.
Something warmer like tan, or ecru, or a pale muddish peach, or other similar hues and values would probably fall right into favor with you. It's a great block pattern and the finished quilt will make you so proud! hope you will share what you did when you finish.
Something like these maybe: (They are less muddy and more bright than I expected, but perhaps you get the gist.)
