Hey, Tom! I had missed this thread, but saw your post elsewhere. Started a new thread without seeing this one ~ oops.
{I'm posting this here instead of putting it in the 'spotlight' - primarily because the recent posting filter "upgrades" won't consistently recognize my profile. I've given up the struggle with it and now just 'lurk' there.}
Anyway, I digress. I like your new project but have some thoughts . . . and in the spirit of your request for input, please consider these ideas.
I like the track nose and the 'caps. But, I would drop the nose a little ~ just so it's slightly lower than the cowl - not much, just slightly. I'd drop those headlights to just above the frame rails. Then I'd narrow the bumper by cutting the horizontal face bar at the outside edges of the bumper guards. And, finally, I'd invert the resulting 'bobbed' bumper so that the bumper guards drop down from the face bar rather than extending upward as they do in your mockup.
I just think those adjustments would visually lower the frontal mass without physically altering the traditional chassis. And, I think they might add some unexpected/uncommon styling cues (especially the inverted bumper guards).
Just ~ as you said ~ some thoughts as to how I would do it. Looking forward to your decisions and the outcome of your plan.
Happy Thanksgiving!
