Well now I know what Procreate looks like and that it's not some weird camera app UI specific to this movie, thanks! Though now I'm not sure if Kaguya is reaching toward the viewer or merely raising her arm; it's the green-ness behind her that's confusing me

Hah yeah, to be honest this is the only one I recognize but it's recognizable enough thankfully.

I think the green bit might be the inside of the kimono? Japanese clothes tend to have a lot of contrast on the outer vs inner (see also Yachiyo's blue outside red inside kimono).
