Hey as a professional mason I'll give you a "good job" pat on the back. I've seen guys who claim to be masons that couldn't do as well. Sad as that may be.

I also do a lot of repairs on repairs homeowners made where I need to remove a large amount of Calk/glue/Spackle before I can start the real repairs. Yours is going to last another 80 years anyways.

Also what was already said as far as the flashing going to leak is very true.
