Some valid points from Aunia Kahn, Gallery director of Alexi Era Gallery,on why it does not benefit your work by calling it 'untitled'. To add: get feedback if you can't come up with anything on your own. Ask your friends, family and fans for title suggestions. In my opinion, the work is not finished unless you've come up with a title. 'Untitled' is lazy and unimaginative. Listen to what she has to say on the subject here.
