sorry i don't know how to rotate. this is a from memory doddle, just something i created when concentration abandons me, however this does show the results of the drawing from life, you can see the frame of the drawing skeleton and the normal skeleton of the figure, even though the figure is monstrous and deformed, that is as a result of taking the normal proportions and changing them ever so little, as a result you can tell it is human in origins despite the bird skull and the elongated limbs. the shading learnt from the life drawing shows not only emphasizing the shadows of the figure but also the highlighting the light parts as well.
