Elevated thoracic bridge form check

Been doing the TB series for about 6 weeks and want to make sure I'm on the right track. I notice the bend is pretty sharp in my lumbar spine and the thoracic spine is looking kind of flat. Do I need to elevate my feet even further to work the thoracic or should I just stick with this position and wait it out for the thoracic to start to bend? I'm already using a countertop, which is pretty high. Any constructive feedback is welcome

Elevate your feet higher.

Thanks, Coach. Looks like I'm going to have to use the wall because there's nothing else sturdy enough in my apartment. Although maybe I finally have a reason to figure out how to set up some stall bars...
