My own spin on Rainbow Dash (Second sprite, constructive criticism please!)

[Ivyleaf1212]

Protip: Scale it down. It's way too big for you too handle. Not even I would tackle such a huge piece as pixel art.

The anatomy is really wonky. The limbs bend in the weirdest ways. Her "upper arms" are fat, the hind legs are broken, the wings grow out of her shoulders (FiM places wings rather at the back, in some frames at the butt, but never so far at the front). The neck is fat, the head is small. The ears don't look like pony ears at all - don't get them confused with cat ears, there's a huge difference! And don't get me started on the wings

As I said, it's my own spin on things, so it's going to look weird.
And I'm not sure how to scale it down without redoing the whole thing... How should I?
