Here are three pencil sketches, using magazine photos as references. They're not technically one-line portraits, nor are they pure contour drawings either. But I didn't lift the pencil while sketching.
Noses are hard, and I see I didn't get the eyes right on the last one at all! Still, overall, I'm happy with this set. It's good to be practicing more frequently.
And just like that, I'm caught up...for now.
