I personally don't like the fat headed ponies
I like there skinny heads, only a few ponies can pull off the fat head (Mrs. Cake, G4 Minty, and Sunset Shimmer)
Others... not so much (Fan Fave Lyra, Masquerade Rainbow Dash, and
pony)
As for the ears, I don't have a problem with them, it just makes em look like cats.
