The term "art proficient" is typically used to refer to someone who is highly skilled or talented in artistic pursuits like painting, drawing, or sculpture. However, there are several antonyms for this phrase that describe the opposite end of the spectrum. Some possible options include "art inexperienced," "art unskilled," "art amateur," and "art novice." These terms suggest a lack of experience or skill in artistic pursuits, and may be used to describe someone who is just starting to learn or who has not yet developed the same level of proficiency as more experienced artists.
