Nice! And yeah, I'm glad someone else sees my point about the LL position for the parade. The only time I did that, I was rather disappointed. I think that part of Main Street being SUCH a tight loop also means that the floats swing by you at a strange angle and at fast speeds, meaning you can miss people entirely and yeah, the pictures come out a bit funny.
My trademark trick now is to watch the parade in Frontierland/Liberty Square for good views, then follow the parade down to Main Street and slide past the crowds (apparently people go through the Emporium to do this, which is probably a better idea that trying to slide past all the slow-moving dads) and watch the whole parade from the beginning right before they hit the barn door for backstage. This is probably unfeasible with even a semi-large family, though.
I love the idea of the Ariel float, but the IMMENSE height of it means you're always taking pictures right up at her and you'll never get a close-up, haha. The "spinning" floats are a great way to give everyone a view and so the characters don't have to run about the float with precise timing to be able to be seen by everyone, but I find if you're at the wrong angle you can miss them (one time the Frozen/Tiana section wasn't working right and it spun super slowly, so we missed Anna/Elsa ENTIRELY and I had to run up ahead to get a better shot).
Nice shots of the characters- I find myself always trying to take pictures while also looking up to view the parade "in person" and not through a screen, meaning that a TON of my pictures have heads cut off because I wasn't angling the camera exactly right, lol.
