Adding Texture and Depth to the Bench
To create a high poly version of the bench, I duplicated my bench and then used the smooth tool, changing the divisions to 5. This created a lot more polys on this model so it could hold more detail.
Then I went to the sculpt tools and selected the stamp tool. I had a look through a variety of the stamps available to choose the one best for the texture that I wanted to achieve. Ideally I would have liked a polished wood texture, but the closest was bark so I used that with the intensity turned almost completely down.
