Daily Sketch Day 2

Colin is into the game Warframe. This is the main character from the game. 

A couple "daily sketches"

Colin did these the last 2 days. His current art style is contour drawing. He obviously has a clear "minds eye" vision of what he wants. He starts the drawing in one area and continues an outline all the way around the contour of the character. My style is "chicken scratching" form and then adding details. I have never been able to do what Colin does below. Note that he doesn't draw in pencil to get proportion then go back and erase those lines. This is inked accurately.
