Yeh, nice work alright, not sure if you have any Adobe software, if I have any linework, I...
? scan into photoshop
? adjust with levels to clean up greys (sometimes convert to bitmap, depends)
? use magicwand to select all black, use select similar, or fiddle with until you get what you want.
? then, in the paths palette (yes, there are quick keys for this stuff!), make a work path, you can just use the default 2.0 tolerance if you like.
? in File, export your paths to illustrator, open in illustrator, add stroke (black) and remove white fill. Now you will have an editable vector.
Not sure if this anything you are after and it is one way of a few and very simplified, as always you will need to experiment to get the results you want but it is handy, keep up the good work.
