Fluttershy is my old pattern, Pinkie my new pattern.
The main differences are the nose and jaw, a bit taller head (though a bit too tall), changed back leg shape and a more shapely rear.
Things noted to change:
a bit shorter head
front legs a bit more forward
eyes tilted inward a bit
mouth??? -needs some adjustments but I'm not quite sure what.
What do you guys think? Any more changes I should make?
