Update - thank you for the amazing response, all the support and NG awards! The Patreon kicked up a gear yesterday so now LotD2 starts to make serious progress.
To answer some comments about this particular style, I'll paraphrase my response to one particular comment:
No this cut-out style isn't the new style, but yes I've used some puppet segments for Bitey here. The only reason is entirely because there's so much slow motion in this teaser. I've ALWAYS wanted to do a slow motion scene of Bitey running through the forest. But if you know a bit about animation, you probably know how difficult (and rare) slow motion is in hand drawn frame-by-frame 2D. And there's no way I'm animating 25 seconds of a character in slow motion by hand. If this was action at normal speed (like the Yuyu movie), it would be fbf all the way.
Hopefully you noticed Bitey's hair and the non slomo parts like the witch's cloak, which are all meticulous fbf :P
Having said all that, I'm not the world's best character animator and I've always used tricks or tools (like tweens and morphing) to cut down on pencil mileage or speed things up -- an example here is Bitey's hair. It's about 15 different fbf "tufts" looping at different speeds and lengths. Looks a little bit cheaper, but it's much quicker and easier than animating all that semi-slomo hair on singles.
