Thanks so much for the input!
I was at MAGFest this past weekend and went to one of the OCR panels, and got some more inspiration to work on this more tonight. I mainly just changed the ending like you had mentioned so that it hopefully isn't as abrupt and such. I tried to sort of giving it a bit more energy before easing it out, and ended it on a (hopefully) better chord. I haven't quite gotten the time to work on the harmony fixes yet but those will probably be next!
I don't think the link changed since it just updates the file, but I'll post it here again anyway!
