This is from the upcoming "Metal Gear Solid: Peace Walker"-artbook. Therefore, it's not a scan, it's simply a photograph of a huge print from a page in the book that I optimized and uploaded here.

I thought the artist made it on a canvas? I watched how he draw this effortlessly and in such a short time on the internet.

He probably did paint it on canvas and they just reprinted it. I wouldn't know.
