Can someone help me figure out why this doll http://www.custombobbleservice.com/uploadpic/2016-02/26718-H-1-1.png
does not look like this person http://i.imgur.com/hiiMhqZ.png http://i.imgur.com/hyRDEOq.png http://i.imgur.com/NaRu2UC.jpg
I would appreciate if someone with more knowledge on facial features please chime in and tell me what to let the person know to fix.
Uncanny valley - a phenomenon in which humanoid robots (or bobbleheads) bearing a near-identical resemblance to a human being arouses a sense of unease or revulsion in the person viewing it.
I think they did a pretty good job with the head. If you mean the roundness/size of the head then I don't know what to tell you other than that's the whole point of bobblehead figures. You have to be more specific.
While all the colours and most of the details seem to check out, the problem is that your photo used as a reference is not taken to look like life-like, but is a blueish darkened version or reality. The bobblehead on this picture and also when viewed through normal human perception viewed as a normal coloured object - but the problem is it has the colours of your gf's face on that photograph that is a colour-shifted version.
To fix this, you would either have to ask whoever was making the bobblehead to take into account that the photo you given to them has colours that are not life-like/normal or just use another photo that approximates reality better to get a more realistic bobblehead.
