Wow, right now I kinda feel like I'm the sole member of humanity capable of failing a Rorschach test. Maybe I'm finding it difficult to separate what I want to see versus what is actually there, but I'm just not seeing the duck bill anymore.
For S&Gs, I opened up the first frame of Elon's Twitter video (where we have the best visibility of the front end, and the car is virtually at rest) in full-screen, took a screenshot, dumped it into Photoshop, and dialed up the brightness and contrast (as only a Photoshop amateur like myself knows how to do). This is what I ended up with:
To me it looks like the front is mostly perpendicular to the ground, but slightly rounded from side to side, almost like a blend of the James Anders / sleepyshado renders.
BTW, for those wondering about the back and whether it's camouflaged, I performed the same crude enhancement on the frame at about 2 seconds. It's hard to say for sure, since at this moment the car is accelerating away while the camera is simultaneously panning left, but to my eye there's a kind of frumpiness to the bumper lines that make me think it's wearing camo:
EDIT: Then again, if they had gone to the trouble of putting camo on the rear, shouldn't they have done the same with the front? Hmmm...
