More head studies after Loomis. Trying is to aim for minimal construction and more "intuitive" drawing. Of course practicing construction is still highly important, just that sometimes I would like to draw without them (especially for the easier and more common head angles) as I feel it's a little cleaner and gives the linework much more fluidity.
Head studies in charcoal! I'm kind of a fan charcoal life drawings, especially those beautiful, painterly ones. From what I understand, many of the artists that draw this way uses an abstraction technique for constructing heads (the Reilly head abstraction, I think it's called.) So lately I've been trying to learn from (by which I mean imitate) artists that draw using this particular technique. Thankfully, Stan Prokopenko has an amazing youtube series devoted just for that! I've also been supplementing what he teaches along with whatever infomation I can scour from the net regarding this method of drawing.
That first drawing is terrible portrait from imagination, in an attempt to figure out how to use the damn charcoal pencil. The rest are studies of head abstractions I could find off the internet. Done on A4 copy paper.
