I'm not sure where the reference for these images came from, or if one came from the other or was done jointly between the artists, so don't pay too much attention to the order of the parent/child relationships.
See, i don't have a problem with there being no human ears, as long as there are some in that general area. However since artworks that show the lack of human ears under the hair are extremely rare, i needed that to make up my mind. So yeah, still cute :D And thank you mattaku mousuke for showing me that.
