Art was quite good as I expected, but Blackbeard's arrival was not handled very well. Poor choice of music, Liberation had nowhere near enough oomph to it, and the direction for that part just wasn't very good overall.
Other comments…seeing Inazuma and Mr. 1 back-to-back like that was kind of neat, giant-head Ivankov was insane, the guard asking for orders in that incredibly bored, disinterested tone was funny, and the melodramtic recounting of Buggy and Mr. 3's adventure was amusing.
The part with Shiryuu at the end was great though. Appropriately creepy music for an equally creepy atmosphere. I guess the red sword effects were okay. Dunno if it's supposed ot mean anything or is just there to look cool like how Mihawk's slashes are purple in animation.
And poor Sanji, Robin, and Nami. They haven't gotten eyecatches in forever.
