Although it's not really any help for your semblance and more just nitpicking.. Faunus don't really display any special characteristics associated with their animal side (as far as we know), but they all have night vision. They more or less just display slight mannerisms that are associated to their animal. 

So saying that Leaf has 'this and that' because of his animal heritage might not be a very canon thing..
