The treatment of the bvox is perfect for the era/style.
The main vocal may be a little aggressive and a smidgen too loud.
The rim shot is a bit loud.
Have you considered mixing it in mono?
I reckon it'd sound perfect with everything up the middle and some reverb over the top to get a bit of a Spector vibe.
Cool song!
