Resizing drawings help

I have a character made through vector drawings. I have already drawn the outline and colored all the body parts, but now I cannot resize the finished character to fit into the video screen. If I try to shrink all the body parts individually the black outline gets too thick. Is there a way I can make the character proportionately smaller without having to redraw the entire thing?

Did you try converting your pencil lines to brush and then resizing?
