You have a knockout model who clearly knows what she's doing. I'm sad to see those pesky cars in #4. I think #2 is your strongest, as far as background and lighting go. I'd be tempted to crop more along the bottom in #5, just to go a little bit under her hand and less hip.
#1 for me but all good. I don't care about the cars (let's be practical). Like Katomi I'm not blown away by the B&W, it loses the impact of the colour images.
Super nice set. Great model! I love her " look " in #1. Either it or 2 are my favorites. After seeing the vivid colors of the others, I agree the BW version pales in comparison.
