For the ATG Alumni (over at dA) theme of "sleeping ponies", we have Pinkie Pie sleeping and having a nice dream. I just couldn't stop working on this one when I started it, as much as I liked the idea. I'm not entirely happy with the castle itself, but I like the overall end result.

And in case you didn't know, that alicorn there is Morpheus, Dream of the Endless as he appears to ponykind. If you don't know who that is... go look up Neil Gaiman. Do it!
