Shot ideas

Close up of eyes, camera moves around face i.e http://www.youtube.com/watch?v=98slWr22fas
Feet walking
Camera circles head
When 'Flashbacking' camera tracks quickly towards her face
Over the shoulder
Pans scene
Camera films woman in profile from left/right
Close up of hands trailing
She looks at blood covered hands, blinks, and they are clean
Foot stepping on chain
During flashbacks camera goes blurry/jerky
