Sorry for the wait! Checking now...
-I don't really hear this C -> Eb thing in bars 5, 9, 19 etc... It sounds like the Eb comes in on beat 1.5 just like all of the other ones.
-The chord in bar 15-16 sounds like Gm to me rather than Bb.
-The chord on beat 4.5 of bar 34 and 38 is wicked hard to play in both the left and right hands. I can just about stretch the RH one but the LH one is impossible for me without awkwardly playing both the Ab and G with my thumb. You might want to give that one a rethink.
-The bass in bar 27 should look like in bar 25. Bar 29's should look like bar 30's. At least that's what I hear anyway.
-Bass goes back up the a C rather than a Bb at the end of bars 36 and 40 which matches the bass pattern in all the other bars in that section (i.e. anticipating the next bars bass note). APART from in bar 40 the second time round where it stays on a G. This point sounds annoying because it's only one note and it'd mean you'd have to write out 8 more bars, but I think you should write those 8 bars out anyway because of my next point.
-Why miss out the guitar riffs in bars 36, 40, 36* and 40*? The ends of the phrases sound pretty boring without them to me.
-I think it'd be better to keep the second top note in bars 33-40 to be a G throughout. For one, I don't hear the top vocal part going down to an F at the end, but also I think the G is just more prominent at the ends of the phrase than the F so it'd make more sense to double the G (in the harmony) than to double the F.
-I'm not super sure but the second chord in bar 43 sounds like it might be a Gm7 rather than Gm (same as in bar 47).
-I'm hearing something different for the bassline in bars 41 onwards. Like this:
i.e. I don't hear it starting the bars on a Bb or going back up to a C at the end.
-The chords in bars 57-60, 65-72 should be dim7s rather than dims.
-I'm not sure I hear the guitar going up to an Eb on beat 2 of bars 57, 59 etc. Kinda sounds like it's staying around C still.
-I'm not going to lie, 57 to the end is kind of boring without the guitar solo written in. Especially 61-64 where the RH is doing nothing at all and the left hand is just continuing with the same riff it's already been doing for 8 bars. Basically the end of this track is just a guitar solo with some fixed backings, and here we only have the backings so it sounds a bit meh.
Hopefully some of that is useful.
