Here's my tutorial for lineart. :)
It covers: Perspective Drawing, Scanning, Layouts, Sketching, Composition, Digital Lineart/Inking, Introduction to Vectors, PaintToolSAI and more!
There is music! If you would like to hear MUSIC, just hit the "S" button. Hit "X" to turn it off.
-- EDIT: okay, i was just kidding the first time, the music actually works now. @_@
Hit LEFT and RIGHT on the tutorial to go through the pages.
Hit UP to come back to the table of contents.
If for some reason the keys do not work, click on the flash and then try. :)
