I'm going back and forth on if I want to change the appearance of the tail and toes

Is there a reason its ears are proportionately smaller? Are they likely to be damaged in its environment, or make it less aerodynamic?

Is it indeed slightly less furry than its ancestor?

Cheetahs and other cursorial predators don't need hooves or "proto-hooves", but perhaps you were basing these off more obscure animals, or combining animals of different physiologies. Were you inspired by hoofed crocodiles.?

The Quaxaca is a brocoli-dandelion plant, not a fauna. You'll have to mention it's an omnivore, or eliminate the Quaxaca from its diet.

These are based on Mesonychid (carnivorous ungulate), Chaeropus (which are hooved marsupials), and thylacines.

"Insead their nasal passageways have widen"
That's a typo. It should be: "Instead, their nasal passageways have widened".

EDIT: None of their prey live in Dixon Dunes.

The tail is odd. I'm not sure how useful it would be for a cursorial species.

It's strictly defensive, since they are losing some mobility in claws the tail can whip at their predators, but first line of defense is running

"The females also have a backwards facing pouch, allowing for their joeys to not have to climb into a pouch."

Backwards-facing pouches are the default for marsupials in real life and the fetal offspring still have to climb.

They actually aren’t. They are fairly diverse in setup, with kangaroos and relatives having head facing pouches, koalas have sideways opening, certain possum species lack them, and the phascogales grows temporary ones. The ones that evolved backwards facing ones tend to be: burrowing, aquatic, or predators. This is a predator that evolved from a burrowed so it makes sense to evolve them. And I based the foot morphology off of the I only example I could find of hoofed marsupials: the Pig-footed Bandicoot.

Anyone else gonna point out how this picture is flipped?

It doesn't look flipped to me.
