You're getting ahead of yourself.
I don't know how old you are or how long you've been doing photography but that doesn't matter. The important thing is where you are right now in your development and you have quite a way to go. People want to know that you can deliver something and that you can deliver consistently. If you deliver consistently, they'll judge whether or not the thing you offer is worth the price you charge. If they look at you and think that you're hit or miss, no rate is low enough for them to feel like you're worth it because they'll be judging based on the worst thing you offer.
That being said, half of your photos are forgettable at best, memorably bad at worst. The shirtless guy? Flush both pictures and don't look back. The brunette with the black shirt standing in the field? Lose that picture and forget where you put it. The two of Taylor Chevy? Take them down. She's cute but it's not enough to take a picture of a cute model; you need to take stunning pictures of people (cute or ugly)
Your most engaging photo based on lighting and composition is probably this one:
Make that your avatar.
I realize I'm not speaking specifics. So, why's Whitney Renae standing out in the middle of a field in lingerie? Either you use that location to make it really, really ironic that she's out of place (and make the viewer get behind it)
or you put her in a setting that makes more sense. Anywhere in a domestic setting would be preferable. A bedroom is an obvious choice but you could also do a den. If you want to do irony, put her in a kitchen. Decked out in come-fuck-me
gear, a cigarette hanging from her mouth with a bored look on her face as she stands with a pan in one hand and a spatula in the other… suddenly you have a photo with teeth. It's got a bite and it's making the viewer consider. We see that picture now and all with think is "Lingerie in a field? WTF?"
The picture of your guy without a shirt. You put him in athletic gear and he needs to be a beefcake. He should at least have the body-type of an A&F model (not the little shits they pay $7.50 an hour to fold clothes, I'm talking about the agency models they have in their ads)
. With his body type, he needs to be in a skinny Calvin Klein suit with the shirt unbuttoned and an untied bowtie. But you have to have a wardrobe budget to make that happen. Which, gauging by your work and location, you probably don't have the budget or the access. That's not a slight; you need a really good stylist for that. When I shoot fashion, I have a stylist and that's her job. She can pull dresses that cost $15K and I assure you I'm on the low end of the fashion world. Fashion is an undertaking.
I got side-tracked though. Brick walls are notoriously bad backdrops because they compete for the viewer's eye. You don't want a background that upstages your subject. And your contrast isn't dynamic enough to make it work in B&W. It just becomes a muddled gray blob with a brick pattern in the background; no one looks at the guy. The pattern of the brick and texture of the grass successfully turn your guy into an afterthought. The picture would actually be better without him in it.
Your dressed up photo of Taylor: The sunset lighting doesn't work because it's not on her. It's on those ugly houses in the background (those houses might be beautiful but they look atrocious here and compete for viewer's attention)
. She's better off in the field without distractions. We see all sorts of things in this picture which cause us to question, but none of these questions are ones you want the viewer asking. What's she standing on? Why's she wearing that expression? Is that a pile of manure in the background? what's up with the grass-pavement-grass whatever? Why isn't she in the sunlight? What the heck is she doing there anyway? You don't want your viewer confused by the image. Not for this kind of work you don't. Clarity of intent is what you're after.
Also, a tip: when trees don't have leaves on them, they attract the viewer's eye (for one)
and immediately make us think of winter. Doesn't matter if it's taken in autumn or early spring. So when the viewer sees that, we expect to see winter-like colors and gear. Not colors and patterns best suited for a sailing excursion in FL. Her clothes are too vibrant, too lifelike for leafless trees and grass which isn't yet green. You want to shoot that, take her to your nearest botanical garden where it'll look like perpetual spring.
This will seem overly negative but it's because the undeniable truth is that your composition needs work and you need to know where things are going south in what you've done. Work on that; it takes everyone time to get good at that element of photography. Once you get that, then think about what lighting you can use for a given genre you're interested in shooting.
