Always overlap movements Even if it's just by one frame. poorly made visualization below. Keyframes are represented by *

Without overlap:

Body v       *                                   *              Body turns to the right
    Head      *                                   *             Head turns to the right
 

With overlap:

Body v       *                                   *              Body turns to the right
    Head              *                                   *      Head turns to the right

This makes the movements feel more natural as if they're actually being affected by momentum. Don't overdo the overlapping though.

Look at references. If you can't find any good references online, make your own. Record yourself walking or doing whatever to get a better sense of how it should look.

Try to get a feeling of how heavy an object is based on looks. If you're looking at a character that's relatively thin, it's going to get affected if it for example get hit by a small pebble, like stumbling or even falling over (depends on how big the pebble is). A character that's a little bit bigger is going to have an easier time standing up after getting hit by that same pebble. (also depends on how big the pebble is). But for example if the character i falling from a meters height lets say, a thinner character is going to have an easier time landing because they have more control over their balance. A bigger character would fall over much easier.
