I entered the first competition in 2015 and, while I didn't win or even place, I did make the finals cut and have my work displayed in the exhibition and in their booklet as an entrant. I also received a certificate of participation for my efforts.
Entrants are to be ages 16 - 39 years old. And it's free.
I'm pretty sure I'm not the only illustrator or artist on here, so maybe this will interest some you. 😁
