Definitely a work in progress, (fairly polite) suggestions very welcome
Wow, looks like a lot work put in so far on this work-in-progress! Nice job.
Fairly polite suggestions:
While it's true that, for a lot of these jazzy sorts of LH chords, the bass note "combines" with the chord button to result in the desired four notes, I've found that you don't necessarily have to play them at the same time. So for that first Am7(b), for example, you could probably get away with maintaining the same bass/chord pattern you establish in the first measure (i.e., no need to repeat the A bass under that Cm chord).
(Oh, and you'll want to move the counterbass line under that first A bass note there while you're at it.
)
For the "missing treble chords" part, it sounds like he's just harmonizing the melody a sixth below while doing while doing a chromatic walkdown with single bass notes. So if you had to put chords on top of those triplets, maybe be something like Cm7 -> G7/B -> Cm7/Bb, I guess? Or maybe Cm7 -> Bdim7 -> Eb/Bb? A bit of interpretive leeway there. (Similar trick on the next triplet bit.)
Where it says "chords sound wrong", that is a Gm chord going on there. If you wanted to put some stabs in the RH under the melody, as you are doing there, the Eb + Bb won't really work (and would sound "wrong"). The Bb is fine, but you could drop the Eb down to D, or even raise it to an E natural if you wanted a nice Gm6 vibe there. Or drop both down to D + A for more of a Gm9 sound. Lots of options!
Note that in the version from the video, he just holds the G melody note without anything under it at all. The chords are all in the LH only. (And he misses the last Gm chord button even though it is heard, leading me to think that the bass side shots are all mimes done after the fact.)
The chords you have at letter C are the standard chords most people use there in the tune. But he's not doing that. Sounds more like Cm7 -> F7 -> Bbmaj7 -> Ebmaj7 -> Am7(b5) -> D7 -> Gm Which not only sounds very nice but also happens to be
the chords to "Autumn Leaves"! I'm totally stealing that idea.
Your "not quite right" bit seems about right to me on those two measures, pitch-wise at least. Rhythmically you'll want to omit that first note and then skootch everything over by an eighth note. Slap a grace note on the (new) first note, and you're set.
