Week5 Pencil Style Test

My initial idea about this animation is pencile style, but I changed in the middle.

But suddenly I felt I want to go back to the pencial style

I did a pencil test on my favorite shot and i quiet like it.

However I am still thinking about the shadow of the line, the color of the girl's dress go back to white, and 

1. Should I keep the balck color of the boy's clothes( which means a lot of work)? or white like the girl's and just put some shadows.

2. What if I make the blakc clothes, how to use the lines to represent the shadows, same direction make the image too flate. How to make it more rough?
