I decided to play with different lights. I had fluorescent work light (Amazon) and Nissin Di866 flash (Amazon). I used fluorescent light to show movement in 4s exposure. I set flash to rear sync so it light up the face at the end of the exposure. At the start of the exposure I kept my head steady for a while then moved it forward slowly until flash fired. This way I got ghostly movement and bright face in one exposure.
