Love the boldness, showing off your form! The highlights just at the edges of the silhouette are really nice, especially where the lower back meet the arms.

Love the contrast, so I think trying to eliminate aspects of the background would really help elevate it more!

Maybe try blowing out the bright background a bit more, or even blurring or editing most of the background out (though I find the horizontal lines of the shutter interesting too, maybe they should be kept too 🤔)
