Fingering [Let it go]

[teachmepiano]

I'm using the following sheet music:
https://www.noteflight.com/scores/view/f627e92b7b9207ea42989e11b9455615ce0adbe0
And I'm curious as to what you guys reckon is the optimal fingering in the 9-10 measures for the left hand. Right now I'm playing 35 - 2 - 13, is this accurate?
Another passage I need guidance with is the left hand in measures 17 to 20. Any help would be appreciated.

Well if it works comfortably, I guess it's accurate

For bar 17-20, I think:
5-3-2-3-2-1-2-1-   2-3-5-1-4-2-1-2  5-2-1-5-3-2-1-2  5-3-1-5-2-1-3-2

I dunno, that seems like a logical way to do it, maybe play around with it if it's not comfortable, but I should alright
