Presentation Renders Help.

Chicken Dip

Hi guys, I have been struggling quite a lot to get good looking renders to present my models, so I am here to ask you guys how do you get such awesome materials and if there is anything "special" that is done to get good looking materials. I am thinking materials suck as this


And this



Or even something like LoneWolfs renders. Is Vray involved or is it just Mental Ray and Standard?
Thanks guys
