Art is a subjective medium that can be interpreted in various ways depending on the individual's perspective. In some cases, an artist may be certain of their chosen style or vision, while in others they may be uncertain or confused. The antonyms for "art certain of" include "unsure," "doubtful" and "insecure". These negatives describe an artist who is hesitant or disheartened about what they are creating. However, such feelings are not uncommon, and artists should embrace them to hone their skills and become better creators. By trying out new styles or techniques, they can gain a greater sense of confidence in their abilities and become more certain of their artwork.
