Awhile back I had a discussion with an artist friend about writing artist statements. She said she writes and writes and writes and then edits, edits, edits sometimes down to one sentence.
The same process is applied in all the arts.
The strongest statements are often the elimination of volumes of information reduced to the most necessary elements.
Knowing when your work states its point without decorative clutter and leaves room for the viewer is a balancing act most artist struggle with.
