I'm going to jump straight to the point

it makes the cat seem like they're going no where. It is your first walk cycle though and we all start somewhere.

Right now, I suggest studying animations by other people frame by frame. Lean on that for a few times in till you feel ready to let go, (and /walk/ by your self, if you know what I mean).

also, when you feel comfortable with your walk cycles, try and add a bounce. Like, show the impact of their paws to the ground.

going on to anatomy, I like what you did with your previous piece, this time the cat is too short, the legs are more of sticks. The muzzle is very blocky and can be worked on as well and the body is a bit ridged compared to the normal flexible body of a cat. I suggest referencing cat drawings or real life pictures for that.

Over all, it could use work, but it is a good start uwu
