I would so totally like to do it. But I think I am running empty on time and then this is my Dad's computer and I don't feel comfortable messing with it. You said mixed media though. Can that be a drawing?
well anything is welcome from features to prints, exclusives, gift certificates, stamps, avatars, dA wear, anything that could be offered as a prize and you're a good artist you should give yourself a little more credit I think you'd do just fine in competitions
