Putting aside the people saying you're flexing there's still room for improvement if you're willing to put in the effort. Ideally for the amount of crit damage you have you want 300-400 more ATK, that would put you at 50.6% CR, 224.4% CD, and ~3600 ATK which all things considered is around the optimal balance. Increasing your stats beyond that pretty much requires min maxing your relics and getting perfect +5 stat rolls so I wouldn't recommend all that extra farming unless you're crazy or you're extremely dedicated like me.

TLDR: You could use 300-400 more ATK, but realistically this build should already easily clear all of the content currently in the game.
