Wow. I'm so glad my critique was taken in the right spirit and that I helped
Loving the optional fronts approach you have. And very jealous of your PS skills.
As to which grill do I personally like it's a toss up between to split grill bmw inspired or actually the Aston like one.
Having the grill mirror the position of the headlamps is pleasing to the eye. Also as you have some great straight edges on the lines of the sides and back the grill looks better 'less round'
My terminology is crap so it makes sense. Well done so far though.
