Looks like a smudge tool was abused.
Very small detial and not very colourful makes this set not as appealing as it could be. Its a unique style to a degree, but not pulled off perfectly. May i suggest that you add a bit more detail in the fur and change the eyes a little bit. Maybe make them a little smaller.
I really enjoyed the right eye where the fur hangs down, but its still too large.
Hope this didnt sound harsh. Keep up the good work
