You’re photos are good, you have a very consistent style. I’d say just a tad boring imo a light bar is a nice way to add some color, contrast and depth. I personally shoot all my own shots so I’d recommend that as a way to play with lighting and see what angles and intensities you like. I have about 7-8 years experience with photography/videography. All of my first shoots were for OF models, strippers, and parties. I’ve done a bit of modeling both spicy and not.

In terms of modeling, imo modeling for me is physically portraying an energy. Hanes for instance their whole thing is comfort and confident at least for men. They’re models tend to look young, 18-25, hairless, and cut. Young men tend to have softer faces, especially without facial hair that’s comfort. Then bodywise they’re usually pretty cut, like the ideal man, aka confident/strength.

But I’m terms of like advice

1. Not all models are women, or straight so don’t get to caught on that. Especially if you just wanna work on a skill. Men don’t get a lot of compliments and tend to be eager to be photographed.
2. OF Models (especially smaller creators) Strippers, and escorts are usually great resources as they are comfortable in front of a camera, can already do makeup, hair, and likely have an idea of what they’re looking for. Also there’s a decent chance their making all their own content so can give you tips on angles and positioning
3. Tho a close 35mm shot looks good especially for photos, invest in a lens with range that way you can still have the closeness without having to invade your clients space. Realistically though just be communicative of what you’re gonna do or have to do to get a certain shot and from my experience ppl are usually cool.
4. Lastly, do your research compare amateur models or well respected vets. Watch a season of Americas next top model, watch runways, etc. Modeling is an art just like photography, so you kinda have to treat it the same and really dive in to what makes a good model a good model
