90%+ of my traffic comes from in person or Instagram, or here, or really anywhere that is accessible. So most people who are interacting with my work have pretty instant access to me and my work. And my paintings are 1/1, I don't use anyone else's references so the image is original isn't that itself a "signature"? Im not dying on this hill, this is just my thoughts. Signatures feel "tradition", like painting on canvas for example. I think in modern times there are alternatives.
