High Cheekbones

i am practicing adding depth to my faces with shading...it isnt so easy to capture the subtle shits of light and shaow that make our features look as they do...this was done just with a no2 pencil...i think the cheekbones ar too exaggerted here...i tried to not think too much..to jsut let the pncil glide easily ove rthe paper...let the creative flow do its thing...it is better then the flat faces i usualy draw even though i clearly still need practice..lol
