You mention that you are having trouble nailing the texture. When you say "laminate" flooring, don't you get the impression that it's supposed to be reflective? I know that I do. Be careful not to focus more on the shapes within the wood grain than the actual physical characteristics of wood flooring.
I found this on Google to show what I mean:
And as I say this, I think of the title screen from A Link to the Past.
Notice the mountains, trees, sky, and castle reflected in the water? Wood laminate flooring has a similar property to this. Only while a reflection on water is crisp and clear, a reflection from wood flooring is going to be far more blurry.
I'm sure somebody knows a specific term for this physical property. [Edit: The terms I was looking for are "diffuse" and "specular." I found this
http://www.huevaluechroma.com/021.php that describes it. Basically, the more
diffuse a reflection is, the more soft and blurry it is, like the reflection on cloth or matte paint. The more
specular a reflection is, the more hard and accurate and clear it is, like the reflection in a mirror or a glass table. Wood laminate is going to be more specular than cloth, but more diffuse than a lake of water.]
If I were you, I would go with the simple pattern in the middle, and add a subtle, blurry reflection of whatever you plan to have in the background over it.
