You absolutely can adjust your point, if you find it to be unsatisfactory - in fact, your encouraged to.
That's... definitely not the way you're meant to be going the organic perspective exercise. Each line is drawn once, and only once (and, obviously, it's drawn using the ghosting method). This has us transition nicely into the automatic reinforcing question. Essentially, what that means is that you'll draw a line, and then immediately go over it a second time, usually as a means of 'correcting' it, as a knee-jerk reaction. That's not something we like to see. One, because you're meant to be thinking about your line before you draw it, thus putting yourself in the best position of executing it well. Two, because it helps to become comfortable with one's own mistakes. You'll be seeing a lot of them, anyway. Hence: draw each line once!
