This explains what i was trying to say a bit better. If you look at the same fold on this version of the mini:

It is very dark at the top point of the fold, but blends and widens out towards the teddy bear. But even the lightened up end of the fold is as dark as the shading cast by her breasts. So it remains to be a very darkly shaded crease, but the blend evens out making it look more realistic.
Hope you don\'t think im having a go, but im just nit picking! It would be easier to explain if i took the pic and drew a few arrows on, but im tired at the moment lol
