Ito did the crowd cut

I think Tezuka did Eren at the beginning, credits are in order but there are so many edits here its quite a pain to match each scene up.

If credits are in order, then I'd imagine Naohiro Oosugi is at the very least in this clip (at least for the cut of Mikasa throwing her scarf over her shoulder at :04 - :05 since that's right before washio's confirmed clip which is followed by Ito's confirmed clip here).

Good call. That cut's in the gengashuu and it's his handwriting.
