I'm not trying to be a dick but giving you honest feedback as a fellow photographer to help you improve. You posted too many pics for me to go through the issues I picked out in each photo but some of the things that stand out just from the first few are:
Pic 1 - Slightly out of focus and your lighting is too harsh and blowing the highlights. You also need to decide what the main subject of the photo is because with some of the model's head being chopped off from your angle of view and not having the entire vehicle in the frame it's kind of distracting and doesn't have a main point.
Pic 2 - Good idea but bad time of the day to take that kind of shot.
Pic 3 - Focus is really soft, lighting needs work so it doesn't have that "snap shot" look to it, and the noise needs to be cleaned up (can be fixed with better lighting and a lower iso)
Pic 4 - I really like this one but again the lighting and focus needs work. It's hard to tell for sure but it looks like the main focus point is on her chest/upper belly area when it should be on her face. Maybe try a smaller aperture to bring everything in even focus. Lighting is a little hot again and you lose the top of the car in the background.
Most of the same stuff stands out through the rest of them. I'm not saying they're bad pics just giving you some things to think about and help you improve the quality. I'm not really on here much anymore but if you want any more feedback feel free to email me.
