About "yowayowa camera woman diary"

I found a very interesting web site, "yowayowa camera woman diary".
Hayashi Natsumi takes amazing pictures
where she looks like she's flying or floating in the air.

Her work fascinated me immediately, so I tried to imitate her. 
These two picture is from "yowayowa camera woman diary", shot by Natsumi.

The rest were taken by me.
(The subject is my daughter.)
I can't increase my iPhone's shatter speed.
I really want a camera like the Canon EOS that she uses.

These pictures are better because I shoot them in a brighter light.
