I like the new wood grain, but it is way too saturated. Town down that and add some more detail like Osiris said, and you'll be looking mighty spiffy!
Nails, graffiti, text, scraps/splinters, etc all add to the believability of the model.
I once read an article somewhere, give each prop a story, what has this object had to go through to get to the point it is today? It was made in a factory, and stamped with a delivery address. On the way it was left in a rain storm and suffered from rain damage. Once it finally reached its destination, it was dropped from the truck resulting in a splinter on its corner. ETC.
