I am so excited tofor our dance classes!

I prefer the ballet dance becuause

I've been watching some videos related to thait for a while and it looks beautiful!

This isn't a totally incorrect sentence, but I think "it" sounds a little more natural.

And don't worry about your current fitness, I will get in good shape after this dance class.

You swap between "you" and "I" in this sentence - is Drew worried about *your* fitness or *his* fitness?

Seems a bit weird to tell someone else not to worry about their fitness because you're going to improve yours. Probably both clauses should be "I" or both clauses should be "you"

You don't need a comma because you already have a full stop
