A little too much blue for my taste; blue sky, blue hills, blue buildings... The car doesn't stand out as much as it should, esp. in #3.
There are also a couple of minor technical issues, the starburst visible from the LH headlight in #1, and the hotspot near her elbow (#3) at the top of the rear window. As well, the license-plate masking is a bit of a detractor. I would consider removing the plates altogether, or getting specialty ones made if you're going to do a lot of car shoots.
