Potrait Study 4

I studied this artwork by breaking down Zeenchin's works, from his artworks I can learn many things from how he manages values ​​and how to set good contrast, after I studied his artwork. Then, I think my artwork be better than before.

For my next artwork, I will try to learn and break down the artworks from many professionals and many legends, just like a new professor using chemistry formulas created by previous professors.
