I am not meaning to sound rude, but you can't expect your readers to know who is who with sudle things like eye color and size of their nose. I don't understand why you have all your characters look exactly the same when in reality in the wild there would be differences in tone, size and body/facial structure. Your wolves and foxes look identical. I would suggest revisiting their anatomy. it would make it more clear to your readers
The foxes have less fur and smaller noses. The lines of their bodies are solid, excepting for the elbows, cheeks and tails. Their ears are more pointed(like a triangle), and their cheeks are turned "up". The wolves have more fur over their bodies(see the lines: they are made in a way that they are "fluffy", while the foxes aren't!) and bigger noses. Their ears are more round than the foxes', and their cheeks are fuzzier.
And the difference between each fox is their eye color. There were one with orange eyes, now thiw one, Ilva, has green eyes. And this wolf queen has yellow eyes.
Don't take that personally I just want to help you
