eh, i tried.
Neck needs to go in more, maybe a ltitle more fuz...?
Eye needs to be slightly bigger
Fluff at the jaw line
Rounded ear points.
Don't define everything with lines. Shading helps a lot, like on the ears. Instead of adding that one line, just add shading, and it will show the dip in the ear.
The nose.. Well, it needs to be a little shorter coming down and more defined.
