Once that was done, we had to do some shading. I find this very difficult because I am not that good at shading, but I still gave a shot.
The first image wasn't that bad but could do a lot better, maybe taken away the mouth line to give it a more mysterious feel.
The one next to it was just the shading with out the help of guidelines. This was very challenging, but the effect was okay, just need a lot more practice on shading certain areas and giving the picture a more variety of tones and shades.
