Ok, so you need to do two things for the wood material. First is add a bump map to give your wood grain a bit of depth. Second is to add a reflection layer to the material. See screenshots/process below:
Here is closup of wood as it sands now with no bump or reflection:
Here is with a bump map added. It’s subtle (view full screen to see better) but that’s because there is no reflection so it’s just adding depth to the grain itself.
Here is the bump map that I made in Photoshop using your wood texture:
With the material selected as your current material, in VRAY asset editor you can turn on ‘bump map’ and select bitmap from hamburger menu and browse to above jpg.
Next, for reflections, you can just add a new ‘Reflections’ layer from the upper right hamburger with a plus sign icon. Feel free to play with settings yourself for the right level of reflectivity.
Lastly, see with and without reflections comparison. The final result will also vary based on your light source(s), adjacent geometry and colors and camera position.
