Breaking out of your comfort zone yet
No, in all seriousness it's a good start, just extremely unpolished, so here's the opportunity to smooth the spacing/timing of volumes and kill the rotoscoped look. Only specific thing I can point to ATM is that the leg movement is choppy before and at the contact frame, that's one reason the legs are sliding around a bit. Also, bit bigger hands.
Thinking of it as a side view walk clears up a lot of things, because a side view silhouette reads more. Generally you're just gonna want to revise the timing and the shading with that in mind, helps make the leap to other views.
