1. Blurry (camera movement) It looks like you had a low shutter speed and your camera moved while taking the photo, I would post the ISO number so that the shutter speed would be faster.
2. Love the color of the sky, other then that I am not really crazy about the photo
3. Again It looks like the ISO should have been boosted a little to get more like. It doesnt look like there is lights, but I would have liked to see it with the lights on, and maybe a little bit of movement in the cars.
4. Out of focus.
5. The sky is a little blown out, really does nothing for me
6. Again really does nothing for me, I would have tried taking with with the car window down, It would have came out better, It would have came out much clearer
7. This is the best out of all of them, lighting is great, you captured the eyes great, and the DOF is very good
Keep on clicking your camera!!
