Challenge for myself draw 100 helmets in one day.

A challenge for myself draw 100 helmets in one day.
I'm actually so regret that I started to work at noon, instead of start at morning, since in the night I was really confused about did I must finish it at one day. but in the end I decided finish it. But I have slept later than I use to.
Oh, and I actually have draw 2 NO.73. so there is 101 helmet...maybe some of it is cyborg.....
