The entire series of photos by André Kuipers, both of the Dragon and otherwise, are stunning:
Though it's a pity that the Progress/Soyuz photo on page 2 seems much more sublime than any of the Dragon photos with the cloudless Earth underneath, with the landmasses and with the two spacecraft pointing down.
That (page 2 Soyuz) is indeed a beautiful shot. Unfortunately the Dragon location is much further away from the cupola than the nearest Soyuz/Progress port, so photos from that angle will be hard to come by.
Hopefully we'll see lots of epic shots when Dragon departs.
