I do like it better, but the strake or whatever its called in the brake duct I think would look better if it was the same angle as the piece running through the main hole. Something to think about is that on a real car, you've either got mesh in that hole, an intercooler in that hole, or all the ugly stuff that makes up the radiator core support in that hole, so if it's too open, you'll see everything in there. Also, you really don't need that kind of area to maintain your cooling. I'm waiting on the Aero thread results myself, but I know that after I did my fascia (only has like a 4" X 14" or so opening in it) I've never run hotter than my thermostat opening temp.
Are your headlight covers going to be the normal ones, or will they be custom? If they are the normal ones, the character line meets up with that lower line that runs down the side. Not trying to nitpick your drawing, by the way. If I saw this car in real life, those are the kinds of things that would go through my head, so just trying to help.
