It was all going so well

I finally figured out a way to put in silhouette style rotoscoped like people, and for some reason at the end it went wrong, it would really help me to film this on green screen with a good camera, so that is what i am going to do next. Instead of painstakingly drawing out each frame i decided it would be fare simpler and far more accurate to first film my person, then use the rotoscope tool the get rid of everything i didn't want then use a fill effect to fill the person in, it think this is incredibly effective but i need to figure out how to put a outline on the person to still make it relevant.

All i need to do now is shoot my scene, shoot someone in green-screen and put the two together.
