Welcome to the Critique Zone! It's an interesting shot and well worth taking. Somewhat limited by the restrictions of minimal editing but that's the nature of the challenge!
Technically: Not a great deal to say, except that I would have been tempted to go for a more limited DoF, right down at f3.5 probably, to make the subjects more the focus of the shot. If you have one, a red filter can help to make black and white shots 'pop' more during minimal editing challenges - this one is a little flat.
Artistically: There are a few things that you could have done differently: The horizon is very central in the shot, which is rarely aesthetically pleasing - up or down would have been better; the Horizon is also almost matched to the top of the posts, which minimises their effect; I would have been tempted to move around a little to spread out the posts, really get the value out of them; the left post and your model are both quite close to the edge, which gives the shot a slightly cramped feel.
These are just some thoughts, but I hope that there is something there of use to you!
Taming the poles with high heels? That's impressive!
Something feels just a bit off to me. I'm not sure if it's the angles, the lighting, or what it is. But I feel this has more potential than what was captured.
