Thanks guys, and yeah the materials still on tests especially for the raspberries
The mats are simple : i use a low translucency value + color correction to modify the saturation and the brightness of the same map in diffuse,
then the spec maps in the reflection map and playing with the value also for the bump map too
here i used only an hdri map in the 1st+3rd renders, the second one i've added a corona light behind the fruits on the top just to ass some reflection and more translucency effect
