Hand Study - Thumbs Up

Here is my new art work.
Delving into something different this time, I decided to make a study of a human hand using my favorite medium, pen.

Applying scribble style, I tried to express myself with various flow of strokes running through those fingers, palm and wrist - with more depth noticable within the wrist.

While other fingers are folded in the palm, the thumb points out signifying a message - more like approval.

The piece was done with a blue ballpoint pen on a cardboard paper using scribble style. You can see my steps below:

Thank you.
