Polina definitely had some underrotated jumps, but I think she's lovely.
She gets good spring on her jumps, so hopefully she can clean up those landings.
I have to disagree about the comparison to the Russian jumping beans, who are all jumps and flexibility moves with no relation to the music. Polina seems to follow the phrasing and her jump entrances aren't *that* telegraphed, IMO. It's a lot of back-to-back jumping, but it is a junior program with lots of elements to cram in.
I think she'll learn to use her long limbs more effectively with time. Lucinda Ruh was also tall and slender but hit beautiful positions.
