yeh i also thought the same mark, when the model is jus polygons (before subpatched) the ears looked way too big but when smoothed they shrink a little but mayb still too big. i have shrunk them down a little now and attached them to the head. but on sum rhino pics i saw this 1 rhino had huge ears - duno if it was a different kinda rhino or not but ill post image later.

thanks neways.
