(Copying over my feedback from the previous submission thread)
This is one of my favorites from Deltarune, so wistful...
-Personally, I don't think that notating the delay/echo effect in m1-6 as accented dotted notes portrays the original song very accurately on piano, the effect in the original is subtle enough that I think it'd be better left to the performer to decide whether or not to include it. A performance note saying "optional dotted 8th echo on melody" or something similar would leave the option open for anyone who wants to play it, whereas writing out all the delayed notes doesn't really leave much room for interpretation. If you do still want to keep it notated literally, though, then the echo in m4 and m6 should be tied dotted notes, like this:

-I think m1-6 would be better written out in 3/4, since the rhythmic structure doesn't really change that much between this section and the rest of the song. If you do want to have a different time signature for this first section though, I think 6/4 would work better than 3/2. 3/2 implies that there are 3 strong beats per measure, but I hear there being 2 strong beats per measure because of the two dotted half notes in m4 and m8 LH. That's assuming you don't want to do 3/4, which I still think would be the simplest option.
-In m2, RH beat 4-5 and LH beat 6 all sound like they're part of a separate voice from the main melody; in order to show this more clearly you could either move RH beat 4-5 to the LH, or move LH beat 6 into the RH in a separate layer.
-m8 and m10 LH beat 1 should be Bb instead of Ab.
-I don't hear the Bb on m8 LH beat 3.5.
-m13 RH beat 1 is missing a Bb on bottom.
-m16 and m18 LH beat 1, layer 1 should be Bb instead of Ab.
-m18 LH beat 3.5 should be Ab instead of Bb.
-It's faint, but m18 RH beat 3 and 3.5 sound like they're missing an Eb and Db on bottom respectively, and m19 RH beat 1 is missing a Bb on bottom.
-m20 RH sounds like it's harmonized in the exact same way as m12 RH.
-m20 LH beat 3 sounds like a Bb instead of a Db.
