This was just an idea i was trying out for masking but I think it looks really good, i like how the previous layers are more transparent than the on ontop of it. I also like that the background is black and white, when i edited this picture i had to cut out the person on the far right, then use the clone tool to get rid of my model as he was on the background picture, then i made the background black and white. After i did this i increased how transparent they are. I think that having the runner get more opaque as he runs worked really well.
