Proportions-wise she feels less like a younger version and more like a chibi version.
I mean, the design makes sense. The AL version of Chesire herself was different than other 'paper ships' aka 'Ships that never actually existed/fully built'. HMS Chesire exists, but it never was a fully-fledged battleship, hence why she's a deformed chibi instead of a loli with proper proportions. At best she was a military transport ship that survives being torpedoed two times during the war, hence the skill 'Bounce Right Back' and the two 'bandages' on the balloon rigging.
