Pink Surprise

First of all - I am a huge "my little pony" fan, especially of Pinkie Pie - so I love that picture, but let's get to the critique:
I like that you tried to imitate the art style of the show, which worked very well although your outlines could be stronger.

To make Pinkie Pie human is a nice idea and also done very well; I especially like the striped socks <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="391" title=" (Smile)"/> *thumbs up* But the feet look strange - you should work on that and focus more on the movement and pose. Since the legs are slightly tilted the right foot seems to overlap the left one at the heel
Additionally, the leg looks a bit too broad and twisted below the knee.

The structure of the ropes fits perfectly into the picture.
I really like the small cute heart which nicely reflects Pinkie Pie's expression and happiness.

Finally, I'm feeling the need of a background which would have given the image more expression.

hopefully I could help you with my critique
