How should the doctor of scp Foundation's beak draw?

Draw with sketch paper and carbon pen. The doctor's beak of scp Foundation should be drawn with sketch paper and carbon pen. First of all, the gene of scp will be Dr. Bird's beak. Its picture quality is not very complicated, and it doesn't need too much tension. Simple display effect is better, just ordinary a4 paper. Then use a carbon pen to make it thin, 0.5 thick. The black flower on the other side is better.
