You go Sina!
Not to be overly-critical---she is very young---but you can clearly hear her tendency to "rush"---play ahead of the "pocket", very common in young drummers. This is more severe when she gets to the "bridge" section of the song.
One thing I learned when I started recording with younger singers who accompanied themselves on guitar is their tendency to rush. Being new to the recording studio makes them anxious, and they find it hard to "wait for the beat" to come around. That playing ahead of the pocket can make it sound like the drummer is "dragging"---playing behind the pocket.
I've done sessions where the producer ended up recording me alone, playing to a click track (a metronome fed into my headphones), to get a basic rhythm track. He could then take all the time necessary to get the singer's guitar part right, without having to pay me while doing so. Time is money.
