They look more like Apple's emoji, and that's a good thing. That consistency makes the faces all look much more natural and puts emphasis back on what their eyes and mouths are doing. In earlier versions of Android, the blobs would bend, twist, and morph.
Basically what i did was to extract all the PNG files from original Apple font and build a android compatible font based on NotoFont repository. Something like what angelsel did on the previously Apple Color Emoji posted here on XDA -> this link.
