MAPPA really did an outstanding job with the Final Season of AoT, as shown in the key animation books released. This is the second volume, covering key animation frames from episodes 76 to 87 and the Final Chapters specials.
This is a nostalgic flip-through, I forgot that this season had the memes, the epic battle sequences, and the emotional scenes that made Attack on Titan one of the best series in recent times. Highly recommended to get the book (got mine from CDJapan).
