Some genga for this scene surfaced recently. The cuts at 0:38 and 0:43 aren't Ando's.
Whole scene is likely just Ando's corrections. The real tantou here is probably Nishiyama.

Where's Miso? I thought he worked on stampede?

Miso did the scene towards the end before Kiso and Ishigami

one of the best cuts on one piece hisory
Without a doubt, and there a quite few more in this movie alone, probably the best animated one of One Piece. The Shinozuka part was probably the highlight of the movie for me (concerning animation) when i watched it for the first time, it make my jaw drop so much. But some of the best cuts from Ryo Onishi, Yuya Takahashi, Naoki Tate, Akihiro Ota and Yukihiro Urata where close to this too.

I think you mean Akihiro Ota

Yes now i'm going to edit it. Thanks Skippy looking forward to the animation breakdown for this week episode.
I love how 3-Dimensional Mori's cuts feel here. Shinozuka's cut is also great with the background animation to emphasize the movements of the characters.

13話の原画を担当させて頂きました瀬崎です。
主にBパートの渚の卒業式のシーン、Aパートのラストあたりなどを部分的に作画しました。
渚の長い学校生活を締めくくるシーンでしたのでとても緊張しましたが、
渚のために親しいメンバーが集まっての卒業式、皆の気持ちがつまった温かな雰囲気が出せればと思いつつ進めました。
これから朋也と渚が中心のお話になっていきますが最後まで楽しんで頂けると幸いです。ありがとうございました。

Concept art is almost always better than the final product.
