Hand Study - Digital Drawing

Here is my new drawing. It's a study of a human. It's really been a while I tried out sketcing the human hand.

Here, the hand is held up as though being raised with the middle finger and the ones following it dropping down. You can also see some lines of the squiggles going beyond the boundaries of the hand.

I made this drawing with AutoDesk sketchbook application using scribble style. You can see my steps below:

Thank you.
