I didn't think I could attach a pdf due to size, but it seems to be OK if you zip it first, so here's the pdf of your tutorial for your inspection. I think you should upload it, or one of your own making. It is really good stuff!
Before you do that, however, check this section at the beginning (third image):

Try to draw several spokes with opposite orientation (green on this picture) and check how many times they cross:

Is it just me, or have you sort of mirrored the original underlying drawing (where the orientation is like the original)? - While the green spokes, which are said to be of the opposite direction, in fact is of the original orientation.
An easy way out would be to mirror the preceding, second, image.
Or am I simply getting more senile by the day...?
It would be a pity if people get hung-up on this point and leave the whole thing (doesn't seem to be a risk of that, but still...)
