Briefly, nice job using black and white! I don’t know if this is the look you were going for, but to make it look even more like it was from that time period, I’d consider using a slower shutter speed and maybe adding some grain to the final image. Study images from that time period and try to see how your image compares to them. Right now, I think it looks a little too good for the tech they had then.
Composition-wise, more sky, less grass. The swords need a bit more room on the top.
I wish my local Civil War Re-enactment was still being held! They were getting some complaints because of the noise I think. Oh well; it would have been neat to try and replicate photos from the early days.
Hope this helps!
