Concentration Post Update

As previously mentioned, I have decided to change my theme and concentration.  Instead of what I was previously doing, I have decided to take a darker, more scary route.  My new theme has to do with confinement and a lock and key.  In these photos, there will be a physical lock and chain that are confining the subject in some way.  Then there will be a piece of paper with a key on it somewhere in the photo, most likely out of the person's reach.  I am not sure what the principle would be, so any suggestions on that would be appreciated.  These photos are some example photos of what the images are going to look like.  I still have to add the key into both of them.
