That was pretty sweet.
There is just one problem however, all this was useless to me as i cannot draw for toffee :P. If i could draw im sure this would be hella useful.
However the masking thing was pretty cool, i may try that out sometime.
However, these things take so much time, and seenas i spend basically all my time studying/working on my MMORPG, i have little time to work on my flash skills, although i am getting better!
Anyway, good job on this, great tutorial :D. Next time maybe you could write one on telling us how to draw and optimize shadowing, and maybe one on actionscript? :).
