A small tip for the future: include YouTube links to the original song for others to easily check with.
Anyway, good work here overall. Just a few formatting and accidental issues:
- The keychange to Bbm should be at m6, not m18.
- There should be a beam connecting the 16ths on beats 1.25 and 1.75 of m7 and m9.
- When you have the same line played on different notes but with the same intervals, you should generally keep those same intervals. If you look at m10, 12, 14, and 16, you'll notice this is not the case. You should change all the A naturals to a Bbbs in m12, all the D naturals to Ebbs in m14, and all the C naturals to Dbbs in m16.
- m18 & 24 E naturals should be Fbs.
- Watch your accidentals - most of those B naturals, especially on page 2 should be Cbs.
