What kind of sticker do you have on the rear window?

Hello dear forum community, my dear wife absolutely wants to have a sticker on the rear window and that (now hold on to you!!): Hello Kitty… Oh no, I thought that too… I thought back and forth, now I had thought about the following or something like this: Hello Kitty 1 <--- the devils should be white of course!Hello Kitty 2 <--- here the devils should be white too!Hello Kitty 3 <--- also in whiteHello Kitty 4 Oh yes, I have tinted black discs, s omit should be the stickers in white, so only the outer edges!! Otherwise you can't look out back anymore... Anyway, a devil should be in it... It should be 2-clear... Otherwise nothing comes up in the back, or rather another topic... Either way it should look like that. I just want your opinion now! Or do you make me some suggestions, what you could do up the back!? Vllt. something completely different?? I'm open for everything and would be happy, If you're involved in this... one more thing, don't get me wrong... only the woman comes up with such ideas...
