Very nice tutorial. I have one minor niggle, and that's when you say that PVP uses cut and paste. Of course, you're enititled to you're own opinion, and, of course, there are a lof of people who don't like PVP. However, as shown in this article here:
http://webcomicsreview.com/examiner/issue050912/history2.html#scottkurtz, Kurtz does keep his use of cut and paste templates to a minimum. The guy's just honed his technique for drawing these characters to the point that he looks as if he's using templates. He's tried to do a newspaper style comic, and pretty much suceeded.
Of course, that said, comics like QC, and Mac Hall, and all the other comics that have broken out of the tradtion newspaper style format, are more enjoyable to read because the art doesn't get boring.
Anyway, that's my two cents.
