That looks awesome! Now, it probably isnt the best time to point out I have no idea what any of the nodes do or whatever, I just get hit an miss sometimes and have not really tried nodes.. I mean I have sort of had them explained but HOW do I achieve THAT look? I mean I hate to ask but would someone write me like a tutorial of what to put where? If I knew where to start I would be able to tweak it to my own look. But with this look in that picture, what do i do? Like I said, I hate to ask but Im a real dunce when it comes to this stuff.... 

Just to elaborate though, I know what shaders are, I know they are used to make stuff look real and they are made up of nodes, like the glossy or whatever else is there. I just don't really know what nodes do what, I mean I kind of do, but which nodes would I have to use to get that look and where would I put them? I know you guys who understand this stuff probably will be frustrated at my questions but I would really like to learn :) 

If I have the main texture, ok that just say that is all I have there at the moment, so haven't even changed the default settings from V4 so this picture is what I have, what do I do next?
