Heyyo, good start for sure !
The turnaround test; the different angles are looking quite good and well defined, here are some edits i'd make:
-The facing Right, the Belt doesnt correctly rotate with it
-The Facing Up, the Tail floats above the leg whereas on the other angldes, its on the floor.
Now the Walk cycle; Weird indeed, ahah! I'd look into keyframing each main element of a walk cycle:
[Neutral -> Right Step-> Neutral -> Left Step]
After that, add the Foot Lift inbetweens:
[Neutral ->(lift) -> Right Step-> Neutral ->(lift) -> Left Step]
Note: *Whilst one foot is lifting, the other foot is dragging back
Hopefully this helps a bit
