All right my best way of helping for the hand:
first, draw a flask-like Shape
add a sort of rectangle, but the top is rounded
next, add a slightly taller rectangle that has the top rounded
take the first rectangle you added, and try to copy it to the other side of the slightly taller one
then add a really small rectangle that has the top rounded
it should be smaller than all the other rectangles
by the way, the rectangles are supposed to be fingers
after that, look for the first rectangle, or finger, that you drew
cut that finger into invisible thirds
go to the first third and draw a finger going down to the bottom of the flask shape from that line
and then you're done with the hand!
I drew a small, crappy example of it, sorry if it's not very useful/ confusing
