Hi you could try reducing the amount of conditioner you are leaving in and increasing the gel a little bit, plus the girl in the second picture looks like she may diffuse. A lot will depend on the properties of your hair though - fine hair is hard to get volume into without losing definition (I have found anyway) but if I diffuse that helps. HTH
