If I would be very nitpick-y, then there can be just one thing to point at; Flurry's right front hoof. Since the tip of the hoof is the tip of the finger, it should be about the height level of the "heel"...

Wow... I just can't find any other words. It feels so... intimate? Serene? I can't find any word that would match the situation captured in the art piece aboveOne can almost hear Flurry's laughing! And the royal pair is clearly happy, but we all can see they are tired as well. I'd say the emblem in the backgroung wasn't even necessary, because this decent shimmering can only emanate from a walls in the Crystal Empire! All the fur, mane, feathers and even the details on Cadance's crown and on such ignored (as one may put it...) thing as the metal bars of the crib! Seriously were you finished with this in only twelve hours?Also, Smarty Pants got younger sister (or brother?), I guessAlso if you dont mind, I'm going to check your gallery for other awesome piecesPS: I came to this picture by chance and get completely stunned by the fact that this was made by a Czech person. Finally someone from our region who can draw ponies very well!
