I kind of find it funny, but to me, you aged the character as well. Even if it's not entirely intended, it's like the character in the picture aged with the time between these two drawings. In the original she looks younger, almost child like, while the new picture is very adult looking. That's pretty cool.
I also like how you stayed as close to the original as possible while sill improving the overall design. Too many of these are just way too different.
