The cute style has nothing to do with the target audience. It is a reflection of the current trends in the medium. Stuff like Higurashi, Puella and other shows cemented the cute look as norm nowadays. This is what people like now. These are the kid of designs people like at this day and age. Moe is not new term and it is not a negative term. There were moe characters in the 90s, but the trends were different. Eternal has cute style, true, but it has most of the features of old moe style. S3 was exactly what new moe trends offer - flustered glowy cheeks, bubble hair, over suturated eyes. This style, especially with the glow on the cheeks reminds me of a certain genre that is definetely not for kids. The new style is way prettier and better done moe style that evokes magiral girls thoughts instead of lolicon shows. The moe style is in any genre, people like it. It is in bloody thrillers, horrors, shounens, jouseis. It has nothing to do with the target audience. And no, Eternal has inspiration from the 90s but we still don't know to what extent to judge it for it. As for style as much as I like what I see in the trailer, looks nothing like the 90s show. Target audience for Sailor Moon Crystal are obviously adult women. Look at the merch. It is way too expensive to aim kids. There are make ups, clothes, bridal dress, jewelry that is actual jewelry. It was also a late night anime for season 3. As for the artstyle itself - it is season 3 based, but with the iffy stuff removed, Balanced proportions, eyes that for once look like the manga's eyes (If Sakou did the eyes like this nobody would have called her take lifeless), no bubble hair, no frog mouths, I do not see how Eternal design makes them look younger. They do in the first concept art, but the actual style in the trailer looks a bit different.
