Overall you are doing good with what you have shown.

Thanks guys appreciate the positive feedback definitely have alot to learn doing sheetmetal all I have to go off of is what I read online and learning from my mistakes. That's why I started with the firewall before moving into the cab corners and shaving the passenger cowl vent.
As for keeping the heat out of the panel. I tacked all 4 corners, then the center, then overlapping tack welds for about a inch off the original tacks in a star pattern
(like tightening lugs) until I had every tack overlapping.
I really should of just filled each hole or at least make the patch panel slightly bigger because the double rows of weld was so I can have something to blend into. Which in the end turned out to bite me in the ass when it came time to grind everything down.
I ended up using my die grinder with a cutoff wheel then blend with the angle die grinder with a roloc on that panel. Not happy with how it turned out but did learn a lesson about being lazy.....
Currently I'm on the fence about cutting that entire section out and and replacing it.
