Cuz why not?
Ok I'm terrible at describing things and this was something that my dad showed me but I'm going to do it digital cuz it will be easier so yea here it is

1. Drawing Da Base

I draw two squares as the base for the palm(red) and the fingers(pink)

2. The Thumb

(I was 2 lazy to crop)
Draw the circle for the thumb base

3. The length

Some peoples thumbs are short or long or whatever so I drew a line to indicate how long it is

4. Finished thumb

Curve over the circle and go straight up slightly curving to the right then back to the left and then go down curving over the other half of the circle

5. Da Fingers

Draw four lines for the the finger

6. Finger

then you go around the line outlining the finger

7. Other Fingers

Then you do the same for the other fingers

8. The Wrist

Then you just draw the lines on each side and on the center to show that your like showing that your hand is stretching outward

And that's it, here's some like examples and stuff.

Hands aren't perfect so it doesn't matter if their like claws or stubs or maybe even have three fingers, as long they resemble fingers then your fine, at least your learning and getting used to it :V
