Picasso art portrait

For art we have been learning about Picasso. We have been making our own Picasso art. First we took a photo of ourselves and then we used maths shapes to make our Picasso art. Then we made it 3D by going around it in vivid. We put pastel on our portrait and smudged it for effect.  It was very hard on my hands. my one is ok but some of the lines are not straight. I found making the 3D shapes hard.
This is my Picasso picture.
