Portrait day today! Quite hard actually, and took me quite some time too. Need to draw more faces from angles and try and see if I can get them done in charcoal too or in another medium.
The top 2 first sets are drawn from ref, the bottom ones, with the numbers in the order they were made, are done without ref. A long way to go still XD But fun to learn. Oh and the bottom ones are done with the directions on the singularity meme. -EDIT- Placed the bottom ones in the original meme.
