Can I level up now?

Puppets are all about the dangles, man~

If you want a loose feel, then all you need to do is try to make the limbs be as affected by gravity as possible. This means that they'll, for the most part, be bending downward (so like, for the sword, it'll more likely have the tip resting on the ground rather than it aiming forward like you have it right now).

Puppets are also all about joints; the arms should be more disconnected at the joint, maybe even to the point where the joint's stretched out a bit more to exaggerate that it's a pin-socket connection. Same thing with the shoulders and the legs; exaggerate the disconnect between the joints, and be sure to have the pieces trend more downward since the only thing that's really holding the limbs up are torsional forces from the strings.

Finally, since you want a puppet, don't be afraid to outright make limbs go out of control! Strings can only control so much of the limbs; they're still probably gonna rotate a bit about the sockets and rest in unnatural positions (so like, for the feet, you can have one foot dragging backwards and twisted behind the puppet. Remember that the feet aren't actually holding the puppet up; all the force'll be in the strings). You don't need to emphasize this on every limb, but doing this to one of them might give off the impression that he's just a toy!
