Feet

Here are some points to note about the foot.

The inner ankle is placed higher than the outer ankle, which is also farther to the back.

The little toes curl down, the big toe may curl up a bit. 

The pads on the outer side tend to bulge out a little.

When drawing the underside of the foot it will look much better if you leave the sole open.

Usually only the pads touch the floor.

Well, that's it for now  

Don't let feet be your Achilles' heel ;)

Hands

Hands, drawing them gets easier with practice.
These are some points to remember when drawing hands.

• The thumb reaches to the second joint of the index finger.

• The pinky reaches to the third joint of the ring finger.

• The thumb axis is placed at the palms' base.

• The thumbnail does not face the same direction as the fingernails.

The palm side is concave. 

The back of the hand is slightly convex.

In a fist the fingers are pointing toward the middle.

The alignment of the finger-pads in relation to the knuckles. 

The best way to learn to draw hands is through practice and observation.

That being said I hope you found this post... handy :P
