That's one forum users opinion, don't take it to heart. Probably got a bit of a superiority complex because they won a competition. If it was with the same logo they have as an avatar, my view is it's not a great design
But that's the thing with design, it's totally subjective. So don't worry too much about what others think (whether bad or good), just keep practicing until you can create something you like
And if it helps, Vincent Van Gogh was ridiculed in his time for the art he created. He's probably the most revered painter in history now
