I'm referring mostly to the characters faces and how they are drawn and how they look nearly identical to other characters. Almost like Kubo reuses the face and facial expressions of a character and simply changes the hairstyle or hair color. Some that I've noticed are:

Ryuken's mother and Jackie

Bambietta and Ichigo's boss

Meninas and Orihime

Byakuya and Tsukishima

And besides Askin, Lieutenant Hidetomo looked very much like Aizen as well

And this Lille guy reminds me a lot of Tousen.

It's all just my opinion obviously, but it's just something I noticed.
