Hi Connor, welcome to TP!
Sometimes it also helps to either post less images, or label them. There are quite a few to go through here.
I think 1, 5 & 8 are the strongest images for me.
#1 - I'd be tempted to lose the brown OOF stuff and crop to the hand. The brown blurry thing is a bit too "in your face" for me. I like the expression and the overall pose. The lighting is a bit bland, but that would depend on what you had available.
#2 & #3 are a bit to cliched for me. It's a nice tidy composition, but again, the lgihting is a bit bland. You appear to be going for a dramatic look to your image,s but the lighting is what I'd consider for something softer.
#4 is nice but the subject looks a bit "hunched" in the frame and kinda "plonked" in the middle.
#5 is a nice composition, but the subject appears a little lost in all the white dress. Not sure how I'd improve on it, but with a bit more work I think you could come up with something really nice.
#6 is a big bold dramatic portrait, but the lack of eye contact takes that away. Also, I really am not a fan of the finger-on-lip pose (which is purely a personal thing!!)
#7 Looks awkward and uncomfortable to me. If you;re advertising the jacket and trousers, it's fab, but as a character shot it's not working at all. Looks like she's got a dirty chin...
#8 is my favourite. Really nice pose and composition. Love the expression and faraway look. But I'm a bit confused by the lighting which is why a normal person might like it more than me. There's a splash of yellow on her chest that doesn't translate onto her face which makes it look like you've pointed the light at her chest. It's just "weird" and something only I would probably spot.
My advice would be to tackle one thing at a time. Start with natural light and work on composition, expression and engagement with your model. Once you've got more comfortable with that, work on the light. Once you've got that, try combining them. For me, where you've done well with the composition, the lighting has let you down. It's a great start for a beginner and just requires more practise. Keep at it!
