It actually doesn't look that bad.

If you do want to improve the appearance, add some subtleties to the grain.
Look in the standard wood texture include for starters for some layering
techniques.


Also try with warping at multiple scales (i.e. scale a pattern up/down apply
warp, then scale back).  This can help as well.
