Just a few things that pop out at me, although overall she is doing quite well:
-I'd recommend just lunging on one surface, instead of having her go on grass and the street.
-Try to be firmer with your voice, sometimes you sound like you're asking a question instead of expecting her to trot/canter etc.
-If possible, lunge in a larger circle and do a few straight lines (ie you go with her a few feet so she can go in a line instead of a constant circle)
-It may help to slow her canter down if you held the whip lower, when it's up like that it's active and it can make a horse go faster.
-the trot transition was lazy, if she doesn't respond in a second then you need to ask in a stronger way, typically with a whip.
