This mix is pretty similar to what Snowflake made.
I thougth the sample she published is great from the idea of the setup and the lyrics….hmmmm…love them. Yet the vocal setup of the orginial has the reverb bleeding and the orchestral setup was something I like to put hands on.
Thankfully Madam Snowflake uploaded half dry on my ask. Thank you.

So I deverbed those as much as possible and did quite some extensive polishing on them with a new reverb.
I imagined her in the middle of a stage standing with an upright bass.
The piano line is panned a bit to the left (replayed). And the first chair chello and violine plays along visited by the full string section later.

A little late for Christmas - but there will be Christmas next year again. ;-)

I hope it makes sense.
