This is very good. My only critique is the choice of notes on the piano at the beginning at 0:07-0:08, I think that E flat doesn't belong.
Your notes are:
B-E flat-A-B
A few other resolution progressions:
B-F sharp-G-B
B-F-G-B
B-Aflat-G-F (descending patterns can give some context, and also naturally imply resolution).
B-D-F-G
That note is literally the only note (and when it is repeated) that feels out of place to my ear. The rest all works and fits.
Great work, great atmosphere! I love the use of the erhu.
