You have some serious skill !
Seriously though, you fixed so many issues with Audi to bring it up to almost perfection! Firstly, I think Audi would look better with the emblem on the hood for all models like you did. It's modern, and a refreshing change. You also gave the headlights a different shape because at the moment while Audi always has great assemblies with LEDS, the actual unit is always the same rectangle shape.
I would make a few tweaks but its great to see this effort from you.
