1st image I was not very happy with and so the next 3 are of me working on edges at the 2 value stage. Critique and tips on where the edges look odd or lost the rolling form effect would be much appreciated. Obviously any other issues point them out too (like angles of eyes or feature placements looking odd). I can already tell the 4th one isn't 2 values since I focused too much on the eyes and made them darker than the rest of it but that's OK, just a reminder to step back a bit more. If anyone is interested then these drawings are for the Watts Atelier Head Drawing Fundamentals lessons so still a ways to go with these. Still getting used to charcoal and Wolff's carbon pencils. PS: my phone camera makes some images super contrasted and others really dark even though all were taken at same time so sorry about that.
