Expired VFR from above:

Think about “aviate, navigate, communicate” and add to your pilot procedure. For example, the first priority is that the pilot in command establish straight and level flight.

Also, relate that descent to things people know, such as the typical max climb and descent angles passengers experience and the maximum grade found on US interstates.

Your work is pretty good. I encourage you to pick up the textbooks used in flight school. There’s lots of ways to be a pilot without actually obtaining a VFR license, such as a recreational license or MS Flight Simulator. You can even get a taste with a type of skydive called an “assisted free fall”.
