If it is as pictured and DS, then I think your good. The red mouth does not fade out across the face and the hair is blonde. From what I read and looked at, fakes often have a red mouth that fades out and a bluish tint to the hair. And it looks like mine from a distance, so it must be legit.
The picture is too far away to see the wording on the bottom left building. IIRC, there like three words on the original and cropped to two on the fakes.
Of course all of this is subject to the old IIRC (If I recall correctly),
