I have redone my seats on my Z with a Ztoyz kit and your seats are NOT properly done. The leather is loose and wrinkly in places. It SHOULD be tight and smooth looking. I had to work my seats for hours to get that look but it was worth it because all the stitching is perfectly lined up and the leather is tight as a drum on all pars of the seats. One tip i could have given you was to drop the Hog rings and go with heavy duty zip ties. The Zip ties allowed me to gradually increase tension on the fabric while heating and massaging it into place, then just zip it in place tight as a drum. The zip ties allowed me to use more of them and spread out the tension on the attachements points to get that tight look with no wrinkles. And they hold up forever in this kind of application.
