I am a fan too but it would feel weird to me to use KK's picture as my avatar. I understand that people want to put their favorite images and use 'em but really it is not that informative. Your (Leonie) avatar is much more informative even though I can't tell if it has anything to do with the real you. But billions of Keira fans with more or less similar Ids and avatar pictures doesn't tell much. Okay, perhaps I am making this a bigger issue than it really is.
Always dream and shoot higher than you know you can do. Don't bother just to be better than your contemporaries or predecessors. Try to be better than yourself.
