I didn't change the accidentals because I assumed that finale was right (I have no clue what the difference between a G# and an Ab is) so I will fix everything.
Generally, the point of writing notes out differently is so that the performer can make sense of it more easily. An example would be with how you wrote B#, when it is generally recognized to be C. A rule of thumb (from what I've recently gathered) is that you write flats when going down, and sharps when going up. There are some exceptions to that though (I don't have an example for one)
Also what did you mean by the /8 at the end of the tempo marking?
Like Altissimo said, I meant 127 or 128
I put the clap in with both hands b/c you have to use both hands to clap, but I may be wrong again.
I think that since the majority of people will infer that you use both hands, it's fine to only write it out in one hand. You could just leave it in for now and see what the updaters have to say once you submit it
I'm really inexperienced with MuseScore and am only Grade 3 AMEB(Not Year 3 school), so I was a bit confronted by the whole 2 voices thing... I'll give it a try though. Thanks!
If you're still confused, I meant that there are some parts that you omitted that could be written in (for example, there's a part that plays chords at the end of Title Theme)
BTW I'm sorry about the A# thing. I meant that you should change it to Bb, not Gb. If you left it as A#, you would need a cautionary accidental for when it goes back to A anyways but it should still be written as Bb
