I think it's a bad idea for her to attempt to sing this kind of music...
It's a cute sort of early 2000s throwback style, but I don't think it fits her voice.
Singing this kinda stuff over time will cause too much vocal strain.
People in the comments were saying her previous music was a better fit for her voice...
There's no contest between the vocal style in this song, and the one from her most recent performance.
Lighthouse has a great album cover though, let's be honest about that...

Done in the style of the Smith-Waite tarot, it's hard to lose with that one.
None of it is the kind of music I give a fuck about, but I think it's clear which one is better.
Her voice is obviously very pretty, despite the shite streaming quality of this stream.
You have the typical people in the comment sections saying she seems "lost" and all that typical kinda rhetoric you hear from people trying to judge the lives of strangers.
I'd say she probably is just about as "lost" as any young person tends to be. The only difference is inherent fame, access to money, connections, etc.
I'm just saying... "folky" is her style and to stray from that is unwise. She's probably tried out this new rockier genre because she felt unsatisfied with the reception of her previous music...
The solution isn't to change your genre, the answer is to just keep making more music until she's recognized for what fits her best. It's not like she doesn't have the resources to do that, so there's no excuse.
