Indeed, even I think the equivalent. I took part in both the challenges until and have even invested a decent amount of energy in both of my arts. Yet, I didn't won anything. The judges don't appear be from an artistic foundation to me.
Art connoisseurs/consumers do not have to have an artistic soul/foundation, they only need to have an artistic taste even though it is relative. I believe that your artwork is best according to you, but according to me or other people? not necessarily. A person's personality affects their taste for art and you can't deny it. Will you scold or blame them for not having the same taste?
Entering a contest does not have to win, you have accidentally shown your talents in this forum. Maybe you are the first winner for other members who have the same artistic taste as you. One time you will be contacted by someone who is interested in your work.
So, stay calm and always think positive.
Congrats to the winners by the way,
