I cannot say I was the most productive this week but I did do this couple of doodles in my ongoing study of film noir:
The man to the left is supposed to be Humphrey Bogart from the movie Casablanca (not film noir but still a man in a hat and trench-coat) . Until I did this I didn't realize how goofy-looking he was.
The other is Jigen from anything Lupin the Third. I basically drew him because the Bogart pose reminded me of his character design.
