Good shit. Still waiting on Crown 2019 and Vanguard 2019 ballads. Would do them myself If I could, but why bother when you can do them (much) better :)
A tip I'll give is you should work on Staffing and Score tidiness. Instrument groups should share unified barlines. For example, Trombones staves should all be connected. Another thing I've learned the hard way is to correctly notate technique. The vibrato single "wave" mark is less effective than simply writing "Shake" or a "thrill" line that looks like "/\/\/\/\/\" (though most performers will not perform as a trill, unless it appears as "TR/\/\/\/\". 0:34 Would probably be better notated with a "Bend" (a single note with a "U" shape symbol over it)
