Nice backing track. here's a thought that may or may not apply (ha, ha). Notice that you pretty much have all the instruments playing all the time all the way through. Maybe in different sections you can drop out an instrument or two and just wait for the chorus to have everything playing. I think it will help in the dynamics arena. Welcome to the world of BIAB and it is a good track you've put together.
