The character design is certainly somewhat interesting, but I find that the way the highlights are done on the skin makes her look a bit oily. (This can be helped by either adjusting the lighting in the room or modifying how her skin reacts to light sources.)
The hair is a lot more detailed than other parts of her character (Especially when compared to the ears which is hard to ignore since they are so close together) causing a clash in style. (This can be helped by equally distributing the amount of detail more organically)
You should also consider how the character fits relative to their environment.
