Yup, that's the one! I just find those videos really funny, especially the elders ones. They have elderly people react to Oculus Rift, Epic Rap Battles of History, Unfair Mario, and tons of other things. It's hilarious, at least to me.
The lines are definitely a lot smoother. They just make the whole drawing really clean, and it's an improvement from your earlier works.
However, since I do like to critique things (even if my friends do find it annoying, haha) there are two things I'd like to touch on. The first is shading, since that's always a critique I throw out when a drawing doesn't have one. I've seen you shade drawings before, so I won't go into detail, since that's probably something you just left out because it wasn't something you were working on. The second thing would be some of the unevenness of the color pencils. You can tell how you colored in the drawing, simply because the strokes are highly visible. I don't know how you color it in, but if you make light strokes at a very high angle, meaning far from upright, it tends to color in a lot smoother. If you're concerned about getting a lighter color than you want that way, just continue rubbing, as you'll eventually get the color you originally wanted.
Anyway, besides those two things, it's pretty good! The edges are smoother, and I do like the ink work.
