I like it!
If you didn't want to do so many black squares, you could do them as large squares/rectangles- whatever the biggest shape you can make and fit with the other pieces, and then use your quilting lines to make them appear pieced- but "stitching in the ditch" even if there is no ditch there.
The good news- everything is square. That will make it much less daunting than a lot of quilts!
