Motion Blur

The shutter speed for this photo is 3.2 seconds.I came up with the idea to have two people moving at the same time while one person stays stationary.The person who is still is the main focus point and is not blurred. I thought that it would come out looking as if people were moving through time while the subject stayed the same. Now that I look at the photo it looks as if there are two ghost standing at the top of the stair case looking down at the subject. Its very ghostlike.
