There really is no perfection. Some judges look at different things more closely, like in horses. I showed my Arab once and got first, then another time I got fifth because the judge had personal preferences.
Also, you can have the most beautiful fish in the world but will fail if it isn't healthy.
Same with me. At a county summer show, I got 2nd (but there were only two of us), while at Fair with a different judge, I got first in everything. My mare was an Arab with flea bitten pinto marking. A bit unique.
