Excellent work! Glad to see you used the joist tape too. I do see some blocking between the joists in the joists between the door and window - did you add blocking thruout? It makes a huge difference in lateral rigidity. I finished redoing the large country L shaped porch last year at my rental. The 3/4" T&G fir decking was rotted, as were a couple of joists in the corner. It had perimeter framing in sections, no blocking and no footings in the middle of the runs. It was rather springy when it was in good condition 50 years ago! I did both, along with doubling up the joists above the footing supports in front of the doors, I figured that was where the max loading and traffic would be - moving appliances in and out and such. Rock solid now.
