And your second and third photos are just sloppy, your subjects exist in the frame, but you aren't composing anything, just pointing and shooting. What does half a car and a Johnny Walker logo add to the shot? What are you going for?
I'm being harsh because you can probably do a lot better. Slow down, think about why you're taking a photo in the first place and then actually look at the result and ask yourself if that's really the best you can do.
