Great stuff and a good effort with a new camera.
Just looked at the exif, drop that ISO right down, increase the shutter speed.
The D500 is fairly noisey when it comes to using the ISO so I would keep it at 100 and the F number would be better at about f11 to f14 max.
Camera and lens is the same as my set-up, cracking lens and imo it blows the Nikon/Sigma and Tamron right off with its sharpness.
