Same comments as in the "Phal" post. It does look a bit on the dry side, but it might only need a bit of fine tuning. Does it bloom? Does it have a name?

It looks pretty good, but it should be less wrinkled. I would change out whatever it's potted in pretty quickly, it looks really broken down. While it's not something you can find in most typical garden centers, there are really good mixes online that contain the smaller bark that Oncidiums love. I've purchased from rePotme and Kelly's Korner, and have been happy with both. A smaller bag will probably be enough to repot now and then again in a couple of years. If not, I think this one is so large that the Phal bark mix might work just fine, with some additional misting between waterings.
