Clean up little timing on barrel rolls at beginning. Dips are off. I'd stress a catch and freeze count, followed by a dip count. They're all catching differently and dipping at different speeds so they can't help that they're off.
Does the opening stunt center front spot do anything before the video cuts on? If she isn't needed I would put her behind the stunt or even behind the back left stunt. If she's not assisting and her next spot is really far, why keep her up there to have a distracting transition? It's also a little distracting how far away she's standing from the group when the other fronts aren't
Can the girls transition without turning their back to the audience? Sometimes unavoidable, but I always try to prevent that if at all possible.
Do they transition with their heads down? They either all need to be down or all up. If you want down, I tell my kids to make their chin physically touch their chest to make them uniform. I suggest heads up though to give a look of confidence and make eye contact with judges/crowd. It's hard to sell a routine staring at the ground!
Jumps - work on landing every jump with feet all the way together. The snap down is just as important at the jump! Also make sure everyone's spacing is right and they don't jump out of formation! If they're moving while jumping, then they're trying to pull the body position of the jump before they finish pushing through their toes. The usual comment of point toes, straighten legs and watch timing there too.
Clean up little timing in the elite stunt. Watch flyers motions in the air! If high v's aren't going to be clean in a skill, consider other things to do with arms.
Pike jump, make them all land with heads down or up. One side is down, one is mostly up.
Moving to stunt in cheer - give them a word to set and flyers grab. They're bending, reaching, and grabbing for each other while walking. Makes it look messy and rushed.
Left flyer in the full up is doing something crazy with her arms. It's all I watched during that part.
Watch clapping in the cheer. Make them tighter and cleaner. They shouldn't look like they're trying to catch bugs when they clap! Something I find little ones struggle with!
Watch center pyramid trick girls libs. Make sure they're always straight to the front and her foot is touching her other leg.
Overall though I'm really impressed this is an elementary school. I wish our local elementaries had a team like this! Good luck!
