The only criticism you made about your quilt that I might even see, once you pointed it out, is the square above the cross doesn’t offer enough contrast. While it doesn’t bother me or probably anyone else, if it does you, color it! I have used tea to darken a piece of fabric and you could certainly use a light brown or whatever permanent marker and carefully color it in to contrast it more with the cross.
I love your meaningful quilt especially as we approach the season of Lent. But you apparently are looking for a solution so here it might be.
Now a word of unasked for advice : Relax and enjoy your labors of Love.
