Hey, SgtinManusArmy, here's the sketch you requested.
Just finished it today. I started it last night but was too sleepy to finish it. Woke up a little early, rushed to complete it, before going off to class.
The most difficult part to draw was the head. Argh.. It was ridiculous. I even tried to use the shading from the original picture to figure out the proportions. And I still don't think it's exact.haha.
