Even if it’s supposed to be a full moon those helmets are a bit too shiny imo, additionally the shot has no focus, you are drawn between the shield on the left, the body on the right and the shiny centurion’s helmet.
I think only the guy behind the leader has a helm thats just a bit too shiny. What I see here is that the light looks like it comes more from the side than somewhat above. I mean unless you’re envisioning something else lighting them from the side. I do like the brightness of the picture overall it makes it seem very eery which I’m sure is the whole point. I would like to see the look of the overhead moonlighting tho as that would really wrap this whole thing up with a bow.
