That's really nice! I like the pensive expression you gave her, too -- the way she's looking back as if doubting herself, the splayed ears indicating a lack of confidence, and so on. One imagines that this is Chrysalis prior to the attempted Canterlot invasion, wondering if it really is a good idea; she knows she has to provide food for her changelings, and with the previous attempts not having worked out, this one will have to, yet she knows it's risky, and she is unsure whether it will work out as intended. Those ponies shouldn't be underestimated.
