Wow these are amazing! keep up the great work!

Hey Luke! I think that this is an awesome start! I am in no way a master at the Loomis head myself, but I think that you should try to limit the sketchiness of your lines. Try to make the circle of the cranium in one line, I struggle with this too, and to help I try and do drawing warmups like drawing lines or circles before I start to draw. Overall, great work and keep it up! ;D
