To improve you will have to zoom in. Your picture captures a lot of utterly empty and unnecessary space. I can outline what you’re trying to capture here as : the guy jumping with the axe, the falmer victim, the fire, the shadow of the warrior cast by the fire onto the wall (that shadow is a good idea). So, since those are the things you’re trying to capture, make them fit and occupy the most space in the picture. In your current picture, the shadow, falmer, and warrior are so small and far apart that they’re spread far across the image with a lot of empty, non relevant, rocks and nature around it.
A solution here can be two things. You can rotate the angle so that the falmer, warrior, and warrior shadow are closer together by taking the picture closer from the falmer’s side. Or you could take the same picture with the same angle by stepping back and zooming in to improve the field of view and increase the focus on your characters in the picture. In this case you would probably not be able to capture the warrior shadow though.
