Reflection rendering on custom material?

Hi guys!
I’m having a problem with some custom made material (reflection???) rendering. Can anyone tell me what am I doing wrong? I’m sharing screenshots and a file for reference… I can also upload textures if necessary.
I’m using vray 4.20.03.
I am using basic plywood texture for diffuse, and have used specular and normal maps for reflection and bump.

Also, any reference on what tutorial to see on a topic of advanced rendering techniques for vray for rhino? Haven’t found anything substantial other than official chaosGroup videos.
Thanks very much in advance!

Changed maping type for bump map from tangent space to object space.
