Her big eyes were a selling point at least at the start of her career. I heard her music before seeing photos and I remember being mesmerized when I finally saw her. I think it must've been a picture from the Whatever era. In some photos she almost looks like Alita from the live adaption. Bigger eyes is a big part of what makes her able to be so expressive. Her visual "language" so to speak and the expressiveness of her music also helps. There's really no other artist that comes with that same package. In terms of look, I suppose Asami Konno and maybe alan are a bit similar?

These days "everyone" looks doe-eyed because of filters, so it's not as impactful. Ayu has her natural features, but there was also a lot of make up involved to help achieve the look, and photo-shop for her covers to the extent that she sometimes looks like an alien (A BEST II...).
