I'm not actually familiar with the WED tutorial, but lighting is usually pretty realistic even in the trial version.
A possible exception is if you see light "streaming in" in a visible beam, as if reflecting off dust; that might be a trial limitation.
What I meant by "all versions should look 'vibrant' " is there aren't enough restrictions on graphics to seriously dull the look of the trial version --
here a few unrealistic shadows, there an object that's supposed to be shiny that isn't, but that's all.

If you want to make another "Kabus," the software won't stop you!
