Personally, I'm getting sick of the short, spunky, blonde, pigtailed, "cute" girl archetype that's becoming rather prevalent in yuri as of late. I don't think it's cute, it's not endearing, it's playing on the idea of childhood which is creepy when sexualized, and makes for genuinely annoying and predictable characters. It's an annoying appearance template attached to an annoying personality template that's just unbearable.
Ah Kodama Naoko...
Every time I read her works I hope it will be as good as her mangaka story. Every time I am disappointed.
Also, Kodama Naoko's eyes always bother me. They make the characters look annoyed/disinterested in everything. Honestly, I should just stop reading Kodama's stuff (I basically have), but that yuri tag is so tantalizing, and I always come in hoping for better...
