1. Bikini picture is your best one - it's the grin, like it.
2. Never put someone hotter than your self in the same picture.
3. Get a better photographer, lighting in the last two pictures is not as good as the first two pictures. Lighting is as important as you are.
4. Car guys are going to react to different stimuli than fashion professionals. I am a design professional and apparently reacting to techincal details of the photographs. Is there anything wrong with your teeth? Why are they not showing?
5. I guess you are the right height and weight, right time, right place who knows what can happen - good luck.
