Hi Mia, welcome to the challenges!
During the upload process, there is a "keyword" field. You'll need to enter the proper keyword into that field for your entry to show up when the designers are judging for the contest. Right now, you have it in the description box, which doesn't work. You can go in and edit your upload OR delete it and REupload.
Either way is fine.
Sometimes it takes several hours for the edit to take effect...
