A short Light Set Up Tutorial

First of all, I have to say that I am no expert in working with Daz3D and I know there are much more complexe methods to set up lighting in Daz3D (also with a better result), but I just want to show how I set up Lights in my renders.

So I am open for critics and ideas, but pls spare me with comments like makeing jokes about the simplicity of my light set up. - I know its simple and not very professional....But some people asked me how I do it and if I can make a tutorial.

So in case you looking forward to have a pictures rendered like above, we can start. Otherwise if you want it more complex and more realistic you have to find someone else to show you how to do it (I am still looking for someone who is willing to show me some more detailed set ups for Daz3D, my own.)
