I hope you realize that bondo is a body filler, not really proper for use as an adhesive. I think it makes more sense to weld the piece, or at least tack it to the hood itself then use filler to smooth it out. And quite the opposite to what you said, i think you want less filler in anysituation if you want to avoid cracking.
Personally, i think they both look out of place becasue its obvious that its covering part of the headlight. But Seti, your workmanship looks pretty damn good to me. I think people are critical about what is only light relecting off of some curves.
Actually, now that I think about it, you should make the "eyelids" "droopy" so that they cover more of the headlight... like a drunk or something. Haaa!
