Art is an act of structuring raw materials and is not dependent on external validation. Originality is an occasional consequence of the process, rather than its upfront intention.
If I frame and capture something without conscious plagiarism, it doesn’t matter whether or not it’s been done before. The uniqueness is in the moment and the relationship.
I’d argue that distinctiveness and consistency are more desirable. Cumulative weight adds gravity, complexity and resonance. All leaves are singular, but a tree gives them purpose.
