Suggestions only, not criticism...
You might reconsider the font size and weight, as well as all the wording used on the cover. As it is now, the title is the least significant thing on the cover when, in reality, it really should be the most. You want the title to be remembered so people can find it to buy it.
Right now it looks like a brochure or a class advertisement, not a book cover. I'd make the blue quilt the entire cover, no photo at all, and put the text (no box, just the letters) down in the bottom 25% where the child is looking. Put the double image, photo and quilt, on the back cover with a brief synopsis of what's inside.
Something like:
Stained Glass Portrait Quilts
from family photos to cherished quilts
by Trudy Rhoads
is all you really need to say on the cover.
