Restored Egyptian phonology

I think I finally know enough Egyptian to proceed in my project
of Restored Egyptian.  (My conlang based on a spoken version of
Middle Egyptian.) Please look at the tables below and
tell me if the symbols I've chosen seem reasonable.

I'm not so concerned with _why_ I chose the phoneme inventory
I have (although I'm certainly willing to discuss that, too!).
I mostly want to know if the chosen symbols seem correct.
I want to avoid mixed-case and also special characters, so I'm
pretty much stuck with digraphs.
