I submitted my artwork right before the deadline and later realized that in my hurry what I uploaded was a low resolution preview image I sent to a friend to get feedback on how it looked.
According to the rules my piece would be disqualified immediately because the DPI is below 300, and I can't find any way to upload the correct image, which I have at the ready.
I understand if it's too late, it was entirely my mistake, just wondering if there's any way I can fix it.
