Looks like she is trying to communicate and barely getting through. Bubble represents the noise and the the hand represents who she is trying to talk to but the hand is so large it can not hear her small voice. Such a great piece.
I'm fairly sure I've seen your avatar before. The trouble is that lately, comments and notes are getting eaten on this end. I've been receiving comments NOW from people made weeks ago. If I don't comment, chances are the comment haven't gone through. Apologies for not finding that comment--but there is no trace of any comment at all you have made on my main page as you claim. It's possible your comment simply did not post.
