Acceptance or awards don't necessarily mean a guarantee of always being accepted, a fabluous income, or that the perceived talent you have is much better than anyone else's around you, either. Sorry to say, there's no easy way. Just get over it, develop a thicker skin, dust yourself off after taking your licks and keep on truckin'. Each and everything is appealing in someway to somebody but never means exactly the same thing to every person. Probably the former.
Judges are no different.
Don't let it get toyou. Make sure there are no overcuts in your mat and that any double mats fit squarely inside the frame as well as being properly aligned with each other. If you know you have done the best that you can, you have nothing to worry about and can sleep easy tonight. Know that you have done quality work and accept the fact that a public review is just a personal opinion.
