I'd like you to give me some advice. These pictures are better as avatars. thank you

I like the first one, the witch in Miyazaki Hayao, the little witch at home. But as far as the avatar is concerned, it is better to choose the second one. The big Q version of the little witch is bigger, so people who use mobile phones can see it clearly. The third one is also cute, but there are many friends in general, and you can't tell men from women at a glance.
