It's time for us to unite and arrange a boycott against Maus0728 a under the slogan "don't let him participate in the art competitions"!
Or give Maus0728 a prize immediately, without a picture. Simply because he signed up for the competition. In order not to waste time and not disappoint ordinary participants, giving hope to win at least something. 
But seriously, it would be good for the organizers of the competitions, like Roobet to reconsider the concept of the competitions. Indeed, it is almost impossible to compete with strong artists. Maybe evaluate the idea (or other parameters, for example, the atmosphere of the art or the emotions it evokes) of the art more than the artistic performance?
There are good artist who can compete with Maus. They are good on their own art style and crafts. Other artist won two times in last contest.
It is a challenge for us to do better next time.
They deserved to compete because they worked and studied hard to become better in Art, we should not restrict them from joining.
