Just follow the above link to go directly to my 
fancel resources page.  I just updated the tips & 
tricks page and added a page on color mixing.  So 
now the tutorials are numbered 1-5 and are:

I: Supplies to get started
II: Painting a cel (from a screencapture)
III: Making a sketch to paint your cel from
IV: Tips & Tricks (commonly asked 
questions/problems)
V: Color mixing

The next one's going to be a tutorial on light 
and shadow, but that's going to require a lot of 
drawing and scanning examples, so I can't do that 
for a couple of weeks, or at least until I finish 
my last two research papers.
