I like everything except the cut out of the header panel. It looks...off. Not that I like the stock header panel, it's such an odd piece on this car, I've waged many wars against them (dents, replacement etc) lol
Practically, that cut would be weird because it's 3D, the bits still sticking down by the lights would be way far forward than the edge would be on the center. Would look much different from the side.
There's also the matter that there's a fair bit of framework and hood latch directly behind the center of the header panel that would then be visible, I suppose you could do something to hide it
All IMHO of course! Your car, you do what you want
I want to add a Mercury-esque grill to mine, with the polished vertical bars:
I think that would add a subtle touch of class & make the car more recognizable as a Mercury. I had a photoshop of it at some point but that's long gone. I suppose I'll get around to making the grill one of these days lol
