Well technically you’re right (I think?), it was a still frame. Maybe I should title it differently. I just want to show how much effort is being put into even those still frames.
Obviously animated scenes are simpler but still, everything is very detailed and incredibly fluid.
Character expressions are… well very expressive and portray emotions very well, background art is also absolutely amazing creating that specific summer atmosphere…
In short: A1 studio is cooking with this series.

Edit: changed animation to production
