Passage looks great, but I have some minor nitpicks. First of all the fur is kind of having a life of its own. This might be just a stylistic choise due to xem being being a space cat (and a side effect of space not having any gravity), but I'll link a tutorial just in case
https://design.tutsplus.com/articles/how-to-draw-animals-quickly-render-fur--vector-17833 (I'm not very fond of this tutorial but the bit about fur direction is good)
I've outlined the parts that look off to me in red
Also I don't know how different space cat anatomy is to that of regular cats, but cats generally have shorter limbs and and muzzles (though both of these depend on style) and their necks are a little thicker. This can easily be changed by adding a bit off fur to the back of their head
