Most detailed 2d animated character designs


I’ve been doing some analysing and from the looks of things 2d animation hasn’t reached it’s full potential, nor advanced as much as I want it to. Despite this fact alot of studios have broken away from the the 2d format and gone for the 3d style, which is a bit of a shame because I would absolutely love someone to take 2d to next level and create something that looks like a beautiful painting or illustration come to life.

Anyways, what 2d animated movie or series has the most complex and detailed character designs and do you believe that animators will try to make improvements, or will it be left neglected in the future? I checked out 2D character animation video for some help but couldnt find any. Ple4ase help me out.

Any help will be appreciated.
Thank you.
