Should a similar opportunity present in the future there are things you can do that would possibly improve your image. First; getting lower or even sitting on the ground would put you on line with the coyote’s head/eyes. You’re looking at a downward angle which may diminish the “hunting predator theme”. I notice the tall grass in front of the coyote is in sharp focus, the coyote not so much. Recent Nikon cameras have a manual focus enhancement called “focus peaking”. This is the exact situation it was designed to aid. When manually focusing a red/blue or white “halo” surrounds the area in focus. Your auto focus hit the grass and that is what you got. The grass. I suspect your D3500 does not have this feature but you can still manual focus without the peaking aid…. Put an object in a field of tall grass and practice manually focusing through the growth…..
