It could just be a person who admires your pictures and is either  a total newbie, shy, or not fluent enough in English to feel comfortable commenting here. 

Sorry to inform you all, but  your talent level here is a bit intimidating when one first joins. I know that when I did, I was too scared to comment or post for months. Didn't want to make a fool of myself in front of artists I respected. So I just puddled around. The very definition of a lurker :blushing:

BTW, When did we get Art Charts?
