The one side we can see doesn't show a lot of signs of reentry heating. It'd be interesting to see all sides of the reentry vehicle to see if the heating is localized. It's interesting to compare the most recent photo with the one in this BBC article that is supposedly from the first flight. That capsule appears to be more heavily scarred by the reentry. It's possible they improved the heat shielding but that much?

According to the Encyclopedia Astronautica, the Shenzhou jettisons its heat shield long before touchdown (so does the Soyuz) to lower the landing weight. That might account for much of the reentry scarring not being visible. Perhaps the Chinese aren't using wood heat shields on Shenzhou like they reportedly did with some of their earlier recoverable satellites, perhaps their FSW class.

As for not seeing the parachute, it's possible it is automatically disconnected after touchdown to prevent the capsule from being dragged by the wind. I had that happen to me a couple times when I was a paratrooper. It was no fun.
