Welcome Onionleaf!
I don't know these songs so I'll just give you some tips on making your sheets cleaner.
First of all, great job on formatting! Your quality level is exceptional for new folk.
So without further ado, let's jump in:
1) Passaj-"Pno." abbreviation at the beginning of all staff systems (except the first of course) should not be there. Removing it may or may not be possible depending on which version of Finale you have.
-You can't have a dotted quarter note on the off-beat of the second beat. Any such case should be written as an eighth tied to a quarter. This appears for the first time in the right hand of measure 8.
-Don't forget a double bar line for the key change. (Measure 9)
2) Champa Camp-"Pno." abbreviation at the beginning of all staff systems (except the first of course) should not be there. Removing it may or may not be possible depending on which version of Finale you have.
-"Lightly" note should be written to the left of the tempo marking.
-Second beat, right hand should be a dotted eighth as opposed to a 16th tied to an eighth.
-As before, you can't have a dotted quarter note on the off-beat of the second beat. Any such case should be written as an eighth tied to a quarter.
-Don't forget double bar lines for key changes.
-Your url is off: http://

3) Festive Town-Left hand, measure 25 onwards has some notes being tied into the next measure. I'm going to ask if that's necessary. If not, take them out. If they are, it's fine.
-"Pno." abbreviation here too.
-Don't forget double bar lines for key changes.
-Messed up the url again.

-All rhythm groupings are perfect though. Way to go!
Overall, very impressive for first arrangements. Well done.
