My best guess at it's overall look at this stage...
Here is a version with a more chrome grille (the GM pic almost looks like the grille has dark plastic cross bars but may just be the lighting).
I've also cut the side window arch at the rear to give a bit more thickness to the C pillar.
The grille is not as sharp and defined as it could be. I found a better defined grille...
