I like this pencil sketch of Bruce Lee. Particularly the sharp contrast on his right hand. I had no wifi when I was drawing so I copied him off of the movie cover to Enter the Dragon even though the cover picture was pretty low quality.
Fun fact: While Bruce Lee is known as an Asian figure he was in fact part British, born in the United States and married Linda Lee Cadwell, an American women, who gave him two kids before his unexpected death in 1973.
If you are still interested in Bruce Lee, I recommend you look up his
one inch punch.
