This immediately caught my eye!  Everything is amazing here!  From the soft feel, to the mild black and white, to the things that are and are not in focus, and especially to the look of concentration on her face.  I want to frame it and hang it on my wall so I can see it every day!  You've captured the essence of loving what you're doing!

I think this is one of your best pictures, it's really spontaneous and fun. But it shows you have a bold personality.
