I would definitely suggest improving your poly distribution. Even modeling out some more of the bigger shapes instead of relying 100% on the normal map to sell it.
I would also suggest making the spec for your wood muuuuch darker. Right now it looks like someone applied a coat of finish to it, and doesn't really match the wear and grime you have in your color map. Take some of those grimy elements and add them to the spec as well.
Would also suggest putting more specular love in your edges all over, and ESPECIALLY anywhere you want to create a "high point" in your normal map. Do the opposite for the low points.
The diffuse is dope, but the spec is making it look like plastic.
