Bmpcc4K in low light | Color Grade & General Criticism

Gonna try to keep this short but ultimately, im a complete newbie in the most literal sense.

Could you tear this footage to absolute shreds? Is it too noisy? Too dark? Should I have filmed with different settings? I know the angle isn't the best, but it's the best I could have done with the constraints I had.

I cut my teeth in video editing (Davinci) while doing this - what's the best possible setup I can get to achieve the best camera performance in low light scenarios like this? I know to an extent there's no "correct" look and it depends what you're going for - but given this was my first creation ever, I know there must be low hanging fruit I can address for the next one.

Any help is much appreciated. Thanks!
