You’re right, it looks a little different, but I don’t think there’s anything to worry about.
The goal of this section of the tutorial is to get concentric rings, not necessarily to have them be nice and smooth. You can always smooth them out later by moving individual vertices.
It looks like in your case, the vertices you were extruding FROM weren’t in a smooth circle. So when you extruded and scaled up, all the “non-smooth” parts were exaggerated in the new, larger loop. Also, don’t forget to move the new vertices BACK (as per third bullet in your screenshot of the tutorial). That might make things look more like the tutorial screenshots.
A word of caution, though: it’s tough to exactly replicate the mouse movements I made in the tutorial. Don’t worry if your character doesn’t look exactly the same. In fact, there are a lot of people who have successfully finished the tutorial by making a character that looks nothing like the one in the tutorial (I’ve seen a fish man and an anthropomorphic pig, for example).
hope that helped
