Hey Bill. Nice tune. Glad to see you back on the boards.
Good arrangement. For the overall level, put a limiter on the master output and set it at like 0.95 db. Get all your busses feeding it and don't let the limiter reduce more than about 4 db. This should get your overall output level close to .95 db without too much squash. It's worth a try anyway.
I always love creativity and original songs over super technique so I really like what you did here. The backgrounds work well too.
