I think it might be useful, if only to see how someone else's mind works, to understand why this picture appeals to me.
First, her intense concentration and involvement with the camera.
Her face is almost perfectly symmetrical so that is esthetically pleasing and yet doesn't cause me to think about specific issues, I just stay locked on her eyes.
Her shirt matches her lipstick and teh blush in her cheeks so there is a harmony there.
The leaves close to her face are oof and thus signal to me that they aren't important - and of course they don't get in the line of sight to her face.
The large leaves in the foreground are also OOF and are again a signal that they aren't to be looked at.
The corners are dark and so my eye is kept in.
She is off-center and the part to the right is 'concealed' thus giving a bit of mystery to match the fact that she is obviously partially concealed.
All in all, quite a nice picture, I think.
