Though i'm not an BMW fan I like the pictures.
#1 The sky is a bit blown out and maybe the car is to much in the middle (but that's just personal opinion)
#2 Love the sharpness of the reflection, maybe darkening the road surface would have made the car stand out more? (not sure)
#3 Got a feeling that the background is to like, it distracts from the car.
Overall great shots and I love the sharpness!
