I know I said how disappointing it was seeing them use existing artwork for the last frame of the episode (not including the ed song) but I'm going to reiterate. If we analyze guts attacking with the berserk armor on, when he was inside of the monsters, it seems like his previous pose has no bearing on how he attacks to cut out of them. Not to mention how they really spent a lot of time with that cape fluttering in the wind. But all that buildup to his final armor mold, and they use pre-existing artwork to show what the berserk armor looks like. Like they just decided they were out of time to make a new model for the berserk armor head and just used google images.
