Nice blend of opposites in this pic. The two ponies being diagonally opposite of one another adds a nice sense of push and pull, the bodies are well proportioned and dynamic, and the facial expressions are very deep. This is because they both seem to be in dialogue with one another, but at the same time also not overly effusive. Instead, they both seem to be reflecting and asking a question, or series of questions, candidly (what those questions are remain up to the viewer).
I also couldn't help but notice that Chrysalis is fixated on the white pony, while the white pony is fixated on the caged butterfly. Considering that another caged butterfly is behind Chrysalis (she's not looking at it), I'm guessing this may mean that the white pony may previously have felt trapped or caged under her circumstances while with Chrysalis she either put it in the past (literally behind her), or that simply that she herself has nothing to do personally with that kind of experience (taking no notice or interest in the caged butterfly behind her).
Seeing soft and luminous clouds represent the sitting place of the white pony may be indicative of her scene and circumstances being more idealistic (if unrealistic if unrealistic expectations were placed), while seeing cold rocks and black inksplots as the sitting place of Chrysalis may represent that she thinks herself as living in the real world (not a fantasy), and acknowledges what she is doing.
Yeah It is really strange, unless we were to meat in person it'll be very difficult to comunicate properly, but untill then we will have to accept or reject the layer we call tecnology, the wall will remain steady.
