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?
The art competition is open to all and why would they set such perimeter which restricts good artist to participate? To contrary the best one should actually win the competition and if the team liked his art then it's completely fine.There are total of ten winners and you could see many different one on the list.You can also try giving something really cool and have a chance to win the rewards.I would also say the real competition comes with great artist and it will improve your work and provides motivation to be better.
Giving some restriction will just defeat the purpose of the contest, maybe its good to see how it currently run because for many months this contest running it always end up successful and we can see beautiful artworks came from good artist here. And for this I think there's nothing to be change unless many newbie account spam this contest and submit multiple or almost the same artworks.
