Jazz Ballad in Eb Major (lead sheet + piano arrangement audio & score) - Work in progress

Hello everyone!

I recently composed the A section of an AABA jazz ballad. I wrote the melody and chords, made a lead sheet, and arranged it for piano using basic techniques from the jazz book I'm studying. The harmony is based on John Lewis's "Afternoon in Paris" (the first four measures use the exact same changes).

I'm sharing this work-in-progress because I'd love some feedback on a few things:
1. B section composition: Jazz harmony feels so open-ended that I'm at a loss on how to approach it. Any advice on how to go about composing the B section is welcome.
2. Overall jazz language: This is my first non-blues piece using jazz harmony, so I would like to know if it actually sounds correct and idiomatic.
3. Two really objectionable harmonic moments:
a. m. 2: A Db on beat 4 over an Ab7 chord (a natural 4th against a dominant chord).
b. m. 4: An F on beat 4 over a Gb7 chord (a major 7th against a dominant chord).

These are textbook "avoid notes" for dominant chords, and both are approached and left by leap. I wrote most of the melody intuitively without analyzing much. Once I analyzed it and noticed the clashes, I tried everything to fix them (changing Ab7 to Asus4, trying other substitutions, reharmonizing the whole piece, and rewriting the melody to resolve them by step or remove them). Nothing sounded good to me. I just prefer how the dissonances sound.

I know how unusual, and probably wrong, these choices are (for now, I couldn't find a single example of them in any jazz standard) so I’d love to know if they actually work here, or if they just make the piece sound amateurish.

The audios are myself playing both arrangements at the piano. Part 1 is still hard so I play it really slowly. Part 2 is more or less performance ready.
1. Part 1. First statement of A. Simple 5 or 6 notes voicing with inner note repetition in beat 2 and 3.
2. Part 2. Second statement of A with arpeggios (mostly one octave 1357 arpeggios with some bass note an octave below for depth).

Thank you and any feedback is welcome!
