Keeping perspective

I wanted my advanced drawing class to work with foreshortening and some perspective.  I also wanted them to work with people since they don't like to draw them.  I know I can be mean, and pushy, but someday they will thank me for it.  I was hoping more of them would take pictures of friends or themselves to create the piece, but only a few took advantage of that.
