The last time I seriously played music was on 12/31/1999, but I'll try to give a little help. It sounds to me like the 2nd to last bar doesn't want to resolve to the final chord ( but that could just be me
) I'm guessing that the piece is in E minor, which ends the song on a major chord ( called a picardy third). So I would change the 2nd to last bar to a iv resolving to the I. Use the notes A C & E in the second to last bar which will create a plagal cadence. And whoever ends on the G# should play the A before. Hope this makes a little sense to you. I'm not very good at trying to explain things
But it is your song so do what you think sounds best. Just wanted to say that the Nutcracker Suite by Tchaikovsky became one of his most popular pieces of music, but the funny thing is that he ended up hating it
