Her expression seems to me
Like satisfaction & victory
She sits there silently
Watching her swing
"I'll always keep you under my wing"
she speaks to herself,
"all you need to do is be yourself.
My strongest power
My greatest weakness
My only daugther
You give me completness."

Hope you don't mind me sharing my poetic view of this beautiful picture :) it's amazing artwork, I especially like the background blue so vivid and emphasizing powerful dark brown contours and her light smile :)
Steem on! :)
