I love Jakub Rozalski's work. He incorporates wonderful polish landscapes with a 1920's time period and some awesome mechs. He has some work showing his process on his Artstation site, jakubrozalski.artstation.com. I chose to follow his process of his "1920 - don't play with the strangers" piece. I completed to a point where I felt I learned what I needed to, so there is a bear and a foreground character missing from my study.
