Karosnikov, I know you said "cheap nasty". And I'm going to agree with you. The tutorial image was quite tasty where your 4 layer version has a completely different flavor. Depending on the style of the story, sometime one needs nasty. But Akhiris is clearly going for that clean look without sacrificing the detailed line work. I've been dissappointed with the sketch functions in PS and Poser. Edge detection most often will introduce noise that I originally sought to flatten or break the line once I have reduced the noise. Akhiris, by hand, 8 HOURS! Can you imagine working on an animation @ 24 frames per second? If you go for it, my recommendation would be to first reduce your animation by a third, do the rotosoping, and then multiply your rotoscoped frames X 3 to get the speed back to what it was. It will be a little steppy but you will save a third of your lifetime for soaking your wrist in ice. ; ) I had to rotoscope all the major events of the 20th Century and compress them into a 1 minute open. I had two other artists assisting me with the roto and an editor to help measure the timing so we only rotoscoped the bare minimum. Most of the "events" were done on twos or threes. It took about a month to complete. But we also didn't have any software to do tweening.
