This is the concept work for the boxer character in my Junior workshop game, Left Hook. Left Hook is a boxing fishing game combo where you fish fish up and then box them to bring them down.
These are all the concepts I worked on for player characters.
This is the trailer for Left Hook. It was created by Mason White. This is a link to his ArtStation account https://www.artstation.com/gearheadgoof
