Kathy,
There is nothing wrong with your capture. It's just that at that moment, the scene was low in contrast and saturation, even though you have a good dynamic range--the histogram spans pretty much the whole range.
I don't know if you allow edits of your images, and I can take this down if you want, but I did two very quick edits to give it some pop. First, I applied this curve:
This does two things. It boosts contrast (the S-curve), and it brightens the midtones (the area above the straight line). Then I did something I almost never do--I gave it a substantial boost in saturation to bring out the color in the wood. (Normally, I use vibrance moderately and rarely touch saturation, because it is a heavy-handed adjustment.) Here is the result from just those two adjustments:
I think it has a bunch more pop.
'Getting it right in camera' means getting the proper exposure, depth of field, etc. It does not mean that the processing will be what you want. All images are processed, but if you leave it to the camera to do the processing, it has no idea what the results look like.
I hope this helps.
