I myself suck at drawing, painting and craft art. My only hope is that the jury will find my works funny somehow, and that's why I keep participating.

You have the desire to take part in their art contest and you are confident in that, I really appreciate that because it is not easy for other people to increase their confidence in taking part in this art contest, because maybe only people who are talented and good at painting can participate in this event, but if you feel bad at making pictures and painting and then want to become a contest participant, that's already great
and the way he tells us about His chance is enough to understand that He is enjoying his participation , Love showing people about His skills and some confidence .
Keep it up Mate we know for sure that eventually you'll become more skilled and capable to win the main level of the competition .
I also suck at making drawings and painting so I don't have the confidence to take part in this contest even though when I was little I used to draw a lot but I forgot to build that desire again, the older I get the further away from what I used to do since childhood, don't give up If you don't win, I'm sure one day you will be able to provide a unique work that will make the jury happy with your work. I wish you luck.

You have given Him advise so best to try it also yourself mate, childhood hobby is hidden inside you and at some point maybe your skill also is hidden still and needs to be show off mate.
good luck for you as well.
