It’s interesting how people react to art. There are the ones who follow the art world and know that an art piece besides grabbing your attention usually has something to say. Others less knowledgable just think art is a decoration and should be pretty. They may also be in awe of technique, usually when painting looks like a photograph.
I am happy when my art moves people even if it is to be disgusted, because then I know that the viewer has discovered something about themselves.
