Lovely work. I like the last two shots the best (though the grey bar in the 2nd to last shot is distracting). Here's my critique:
1. You could benefit from use of a reflector a bit more--some of the earlier shots (between the shadow and the bright sun) lose some detail (especially for the model). Shot #2 is the prime example of this.
2. Watch your background. The yellow traffic stops in #2 and #3 are distracting. Some of the background buildings take away from the shot.
3. Unless you really want the tattoos to show, in this case I think they're a distraction from a lovely model with great lines in a killer dress. If you do a second shoot with her, b/c of her tan skin tones, you can get away with using derma blend to cover up those tattoos.
4. Your model has curves. The car has curves. Think of a pose that take advantage of both. Many of these shots are really using the car as just a prop or backdrop (which isn't a problem) for the model rather than having them complimentary.
Nice work--thanks for sharing.
