-symbol is a rose, very similar looking to Ruby's at that.
-silver eyes. once again, like Ruby, and Ruby's eye color has been hinted to be important in some way.
-taking a lot of liberties with the faunus stuff, we have no knowledge of how Faunus DNA works compared to baseline humans so saying being part cat caused her to be a small build is pushing it, unless the build were her only faunus trait. then again, she could simply be a very small human.
-the only time human genetic traits would override the faunus night vision would be in a cross-breed between a human and a faunus, and she appears to be a pure-blooded faunus.
-cats are actually not much faster than people, they only have superior speed since they are quadrupeds, as she is a biped she wouldn't have that advantage for speed
-the fact that she is tiny and adorable, i already have a character like that who exists in this universe, not sure reality can handle that much kawaii(joking)
-lack of text description to supplement pictures, i explained my views on the subject earlier in the thread. to summarise:I'm not particularly fond of people using the work of others for character pictures, but will allow it if a written description is also given. this applies to clothing as well.

As I said, many of those things will likely be fixed as you expand on the sheet.
