The artist who released those Canterlot images from a while back has dropped a few more up on his portfolio blog. These are completely unlabeled, and mixed in with a few non-pony images (at least they look non pony), but you can probably guess roughly where each takes place. Number one up above appears to be the spa, and the ones below look like Dragonshy images.
Head on over here if you want to see more, though again, the last three don't really match the pony style in his recent post. I could be wrong though!
