Was there really only one judge?? Just one?
You are being way too hard on yourself then bud. Ignore it. Really. No close competition can be decided by one person. Such competitions usually have 3 or more judges that come to an agreement. I've been on panels before, and when the competition is close, they often do not agree on the top couple placements.
Just use those comments as best you can and move on.
Oh, and I haven't yet seen the original thread, so I have no idea what went on there.
