Unfinished work.
Yes this is from left field.
I'm drawn to the act of creation. I love work in progress, proposals, and sketches. I feel that this aspect of a piece is the most dynamic, where thought is unbridled and pure. I know that sounds hokey, but hear me out. As you're in the midst of your creative process you're channeling who you are w/ out reservation.
When you begin finishing your piece you start to make conscious decisions that are more intellectual based rather than intuition. I think the person you are during creation is more pure than the thoughtful. This applies to many styles of art, but obviously not all.
My basis for this statement or observation stems from art school. There were plenty of instances where I was watching another student work themselves to death trying to "finish" a piece, when at least to me it was already complete. This isn't just considering over-working a piece, it's what I see as a shift in artist. Depending on what type of art you're producing I think there should be a level of what many would consider to be unfinished. I know at least in my own work if I tried to finish something I'd probably kill it. Who I am as a swift creator vs. the thoughtful detailist are two different artists altogether. Yet that's also based on what kind of work I'm producing.
There's an argument that you simply need to define that artist w/in yourself. That's a distinct possibility, but one I'm not going to subscribe to for my own painting. I can definitively say that I'm am a freaking perfectionist when it comes to design. I guess this is the Yin to my fine art Yang.
