just read this post from the beginning.
It's a dribble... how long should a tutorial be? It's not like it's a multi stage/step cut. It's a set up and execution. DnD's longest single tutorial on the Trilogy was 4:56 with Madonna. Pandora with it's 2 dozen steps clocks in at 9 minutes and change with 2 parts. What you're asking for doesn't make sense to me. At least it wasn't throwing you to the dogs like DnD's System. "here it is in 2 views, normal and in slow-mo... have at it people!"
Moreover, a tutorial should have just the essentials. there's no point to spending film and editing time saying, "Well august 17th 2004, at 6:43 pm, I tried these finger positions with this kind of pressure and f*ed it up yet again! This other time in band camp..." Maybe Andrei should add another volume to his epic set that's coming out on experimentation of his flourishes.
On a serious note tho, if what you're asking for are corrections for the most common mistakes the artist sees others doing when learning the move, that would be valuable information for every flourishing DVD that gets released in the future from a teaching / learning standpoint.
I trust that in a tut, the artist presents the essentials of the cut. I don't want to keep stopping while the vid explains "do this - not this, nor this... and not even this". It will interupt the learning experience.
I appreciate the review though. I'm not sure how many other people were like me: 2 minutes after I hit Submit on the payment page, I thought "OMG, I just spent $23 +s/h on a dribble" *goan!* In the end, it was worth it I thought... at least it wasn't full price.
