Wow. Those are stunning images. Congratulations, I'm sure you can't wait for the big day.
But I have to advise caution with those long ultrasound sessions. I've read that there are studies showing that these long ultrasound session can be harmful to the baby. If you are considering another session like this in the future, research it a bit before you commit to it. I read it in one of my wife's health magazines but I can't remember which one, but I'm sure you could find the same info on the net.
