Unfinished plywood has texture in the form of bumps (non-smooth). I would also try to sharpen the knots, the texture you use is a bit too on the blurry side. It should be as focused and sharp as all the other items in the FOV. The other issue is the bottom end of the hammer handle. It seems too faceted. need a smoother mesh or some post wrk. Definitely getting there.

Pass no temptation lightly by, for one never knows when it may pass again!
