Well... in my opinion the Zorua sprite could use more shading cause it kinda looks numb, and dad's sprite, as like I see it is a sprite made by combining sprites of Hoenn leader Norman which has a E4 Drake's cape. Don't get me wrong, it looks great!
oh! great! you found out that it was a combination, but not with the hoenn leader norman, it can't be because he is even not stading norman^^
but yes your right it's a combiantion of dad and 4 guy of the elite 4, but anyway the elite 4 will completely be new also ;)
if not, for the zorua, someone just told me that on serebii.net there are the battlesprites of zorua, zoroark, and the 3 starters!! so I'll take the sprite from there like this I'm sure to have the original sprite and the best zorua sprite that exists^^
