Thank you, Steet. Yep, it took enough much time (hours), but it was not very hard (I used PAP 4.0 - I guess it's excellent for rough animation (and maybe for some clean) and is very easy to use).
As for pullover, - seating here in chair and modeling this action, I thought it wouldn't move very much - maybe only on last frames. It seems to be very unrealistic moving (rotating) body both with head, seating in chair, in such situation. Anyway, thank you
