Upside down Picasso

In AR135 class, I copied Picasso's sketch. I did my best to make my drawing looks same. 

I used the upside-down method to copy more accurately. I used grid to see which lines are located in which box. Also, I folded the paper. All my class and I did was simply coping the lines in each grid. It was not that hard when there was grids. I still could have almost the same proportion and location of the original drawing. 

My man looks a little more greedy and furious.
