Okay, so I would like to know what do you think about these designs?

Diana Kunikida's official design. It should look simple and like a normal perons clothes. The only typical Anime-related should be the ribbons in her hair. Does it look okay?

This is Risu's design. The basic idea is a kimono with that really big bow at her back. She's a squirrel, I wanted to have some more unique animal in the UTAU fandom. And there should be a contrast between her pale kimono and her strong pink eyes and red-ish hair.

This design is NOT OFFICIAL. This is Liana Kunikida and she is a WiP-UTAU. She should look a bit like... well... a sex worker? The opposite of Dia. Any advices what I could change/make better/leave it as it is?

Thanks =)
