Messing Around With Grayscale Markers

 A bit more vehicle practice. I was going to put something else in the bottom half there, but at the rate I draw... nope. Maybe later. Until then, I'm too lazy to crop it right now.

I wanted to practice some more with lighter, less clearly defined shades of gray. This is the result... I know the top pipe turned out a bit weird. And for the life of me, I can't figure out why the school's scanner darkens everything down so much! It really irks me. The lightest highlights on the pipes there? Those should be pure white. >_<
