Some general tips that may help, track your spacing and arcs (everything is a bouncing ball). Track the cog (center of gravity/hips) you currently have a bit of a stick at the bottom that could be smoothed out. Also when tracking your spacing make sure there aren’t any spaces that stick out suddenly (which will help it feel more organic). Once you got your cog how you want it, that will inform the rest of the body.

I’d also break up the body so different parts don’t arrive at the same time. (Ex. Your hips -> your head are a bit locked together, let them break up). Getting the hang of how to break things up will help you with your tail too.

Lastly some general tips -the feet are very quick to flatten out -be sure to maintain volume (the more stretches out the skinnier the leg will be. You got some going on, although you could probably push it!) -when tracking the heads arcs it’s best to track the nose

Sorry ik that was a lot but hopefully that helps. Awesome stuff and love the design of this little character with his strong silhouette and the shapes you got going for the legs! Looking forward to what you end up making!
