Just take you time and think about your shots.
1. Slightly out of focus, needs straightening, loose the manhole cover in the foreground, move the car (the lamp post looks like a giant ariel). Watch for over exposure on the car lights.
2. Much better, but again loose the lamp posts, the Tiles sign and the bench. Try to de- clutter your background. Good angle on the car though.
3. Location not the best, and loose the errrr... Lamp post. Again watch for items springing out of the cars lines. in the case a notice board. White balance might be a bit off and there are some blown highlights on the car.
Keep these shots. keep shooting and look at them again in 12 months. You will be amazed at how much you will progress
No 2 is the best one here.
