Rear drums too tight

Have you verified the e brake cable is not hanging up?
All listed above also are good points.
Brakes can be a tough item to diagnose with a single picture and not in person.
If you are having troubles is anyone local you can ask who can actually see the work and knows brakes verify what is done?
I typically remove both drums but even after 35 years of doing brakes allways leave one side to verify it’s correct before I jump to the other.
