Magical Art and Candy, May not contain Candy Options

[Shaddow]

So yeah, decided to start posting random things I am doing for your harsh judgements! I've started off by trying my hand at some bigger sprites. My first one I've done so far is this one:

I was trying to capture the same image as this:

[Show/Hide] Image Inside!

Which is a drawing Dragoncookie has done for one of my RP characters. So yeah, basically I'm looking for feedback, did I compare it well, was it shaded nicely? Did I capture everything? Improvements? Insults? Jeers? Er...perhaps not those last two.

[X-M-O]

There are two things I've noticed that are off:
1 - The white doesn't go over her shoulders in the pixel-art as it does in the picture Cookie drew.
2 - The knees seem to be bulging by comparison to her thighs, and thighs are always wider than knees (unless there is some serious bone structure issue). O_O

I still love you despite my insults and jeers!
