This is how I draw heads from my...head. The tricky part for me is getting the initial basic "underdrawing" right at extreme angles. Not going to lie here: I always get the foreshortening wrong.
Which is why I "cheated" and used my magical computer skills to make these guys. I have another 91 heads on a second .jpg for the back angles. If I'm sketching figures, I tend to pin them both to my image board (I love ArtRage. That is all.) and glance at them to keep me from wasting time drawing something stupid.
I know these don't have the normal "oval" head geometry with the horizontal and vertical lines for the nose and mouth...but those shapes and lines are REALLY hard to draw right at an angle. So I simplified: a circle and a triangle in an "imaginary" box. It surprised me how well it actually works... ...but my proof will have to wait until the tutorial is done. For now, if you need some help visualizing a head angle, feel free. Think this is cool? Link it.
Kind regards, C.E. P.S. If this image looks familiar to you, this is why. :
thank you so much for this - I've never thought of drawing heads this way. Do you possibly have this image in a larger resolution though ? I want to try your excercise, but I'm having trouble making out the triangle in some of these images.
