Need urgent help with walk cycle!

Hi, relatively new to Character Animator and have not worked with custom puppets yet. I tried designing my own character on illustrator. But I seem to have issues in the walk cycle. The arms don't seem attached and the walk feels too jumpy and not a smooth movement. And the face warps in a weird way Please help me out. I have attached the puppet file for debugging. It would also be great if you could show me a screen capture of how the debugging was done so I don't have to disturb you again for something of much less significance. Thank you for your time and amazing efforts! I have also attached a video of how the walk looks right now
