IMHO....being a owner of many husqvarna over many years
the design is dense, I actually hoop as little as possible, i use the baste stitch function, I don't use spray adhesive, I either use two layers of stabilizer or one layer of a nice thicker better quality cut away stabilizer, I also agree that at some point it looks like the hoop got out of alignment. Maybe try a new 80/12 needle. I wonder what kind of embroidery thread was used?
well that's my two cents worth
