Owner and designer note:
Hello~ I'm nekomiou. I make three different version. Version one is slightly light, version two is truly dark and version three is mix of both, I think. It's up to you or you can just ask for re-do. Thanks. Sorry that the designer you choose is busy.
 

The one that shown is version one.
