Hulk made with a ballpoint pen on paper. This was made as part of my research process to go on the background of my Avengers paintings.
It gave me a better understanding of muscles of the arm and shoulder mainly. I also got a better feeling of angry Hulk.
I made myself spend very little time on it, so I had to do this fast and without worrying about accuracy and proportions. I am happy with how it turned out though.
