I'd delete this. Not flattering to your face, not a professional photo.
Awkward pose, unflattering lighting, doesn't show off your body- just doesn't really have a use.
Again, not a professional photo, and no real purpose. Cute, but kind of like posting a picture of you and your cat that your mom took. Just doesn't belong.
Really, I'd only keep these:
I'm not much of a fan, but it's the only photo that shows your legs. Try to get a good full body shot at your next shoot to replace this!
This is nice. It's good to keep an updated no makeup shot!
This is cute and I know what your tattoos look like.
I would make this your main photo. Very nice.
Shows a little personality.
Let that come out in the shoots you have coming up and replace this one with a professional one.
I'd keep one of the smiling candid ones, but you don't need both.
Best of luck!!!
