Was Zion Canyon Road open to public traffic or was it shuttle bus only? Because it looks like you didn't get down into the canyon, or maybe you just didn't post those photos? If it was closed to public traffic, I highly highly recommend you park your car at the visitor center and take the shuttle bus into the canyon. The drive on the main road is nice and all, but I think the true beauty of Zion lies in its canyon. If you have time for other spots, great, but at minimum, ride to the final station Temple of Sinawava, and take the River Walk Trail, which is a flat and wide and paved trail that follows the Virgin River along Zion Canyon. The views down in the canyon will blow you away.

Also, if you plan on visiting 3 or more national parks within a year, buy the America the Beautiful national parks annual pass. It's cheaper to get the annual pass than to pay for 3 national parks separately. If you've already paid for one or two of the national parks, as long as you have the receipt, the ranger at the fee station can put the money you've already paid as part of the payment for the annual pass.
