I don't like that angle. For full front shots like this I generally try to be at eye level with the "driver", so maybe a foot lower in that picture. Sexy car!
they aren't doing much for me, either. maybe different angles. I would shoot the Mercedez again, but IMO there's nothing really special about a - what's that, a Camry?
They aren't centered or completely level. If you're going to take a shot straight from the front, it really has to be completely from the front and not off to the side a little either way.
