I've reconsidered my tasks and think that getting all the keyframes done is my priority as if face dire situation I can hand them off to trusted peeps for inbetweening. Then I'll plan my next move, but definitely animation should be done by the end of February (early May is the red-line, totally, absolutely cannot be later than this deadline for animation.)
ps. If anybody can guess what the colors stand for, applause for you haha.
