What did I miss this time?

Every time I introduce a new arrangement to our ward choir, I always say, “Alright, let’s run through this and see how many mistakes I made.”
Though I try hard to catch them all, I still miss a few. I forget to put in a rest. I forget to dot a half note. I put the glissando on the wrong side of the notes.
So, if you find mistakes, please, PLEASE tell me so I can fix them!
