Hi Wayne,
You know that you will have to cut away the damage part on the pectoral fin, for it to heal properly.
The damage on the gill plate will leave a scar which will not go away.
As always it is difficult to judge Koi from a photo, but I noticed a few things.
The sashi on the fish should have stabilized by now, but an overlap of about two to three scales on both the Hi and Sumi is still present. Some Hi also bleed into the tail.
The Shiroji is good and I like the head pattern.
I think you paid too much.
