Some of your pictures are not bad.
Composition in most pictures are real good (IMO). Lighting and white balance you need to work on. Stop over-editing. You’re over-doing it with the contrast on some pics. Some of your subjects look yellow/orange. Some pics have harsh shadows. I’m going to point out a couple of images that I thought stood out to me as having a lot of potential and give you an example of something that you can work on
My favorite picture is:

Lighting is nice (a little tiny bit off but not bad at all), and the model is not half-bad to look at even though he looks a little bored. My only real complaint is his skin tone. It looks unnatural and orange. If you shot this in RAW, you can still fix this and get a nice color. Online there are plenty of resources and you can read up on white balance.
My second favorite:

Beautiful subject. I love her tattoos, her dress, her make-up, her hair… she is super cute. Location is nice. I would just say that taking a shot of a model from below can be a little unflattering (can create a double chin, for instance).
You’ve got a lot of nice portraits but like I said, some things can be worked on.
BTW, I am not a seasoned professional or anything. I’m just passing on to you things that I’ve learned along the way. I did a photoshoot (of someone who couldn’t afford a photographer so made me take pictures of them instead in exchange for some of their mother’s cooking) and I overdid the tilt thing… I think 8 out of 10 shots were tilted because I thought tilted shots were “professional looking” lol. I’m sure some real photographers may be able to give you better critique.
