I offered my services for a possible commission on lulz.net and some rather opinionated people said my muzzle and head structure was one of the major faults my art had. So instead of endlessly fighting against a tide, I decided to humbly accept my faults and work to change them. Here is a sheet of heads and muzzles I did for practice. I'm also going to be focusing on making sure they are correct when I draw from now on.

This was actually all done in black pencil. I used a color range selection on the grayer, lighter lines and used a hue/saturation colorize layer on them to give it the "sketched with blue pencil" look.
