We just finished up the portrait class I was teaching on Tuesday nights (thanks for posing Anna!). During the 10 weeks of the class I was able to do some head and hand studies. (Side note: If you're wondering, part-time/evening classes start again the week of September 14th.)
In this drawing, I was experimenting with a limited palette. I like some of what's going on in here, the warm and cool reds, the yellow shift. I was also experimenting with hatching direction.
Since I made this study on newsprint, it will degrade faster than if I had done it on acid-free or pH neutral paper (good thing I have a scanner). Newsprint is great for practice though because it's inexpensive. I've also been known to use printer paper.
