This artwork is part of a series I created for a friend who is a fan of the Winter Soldier. The series consists of five pieces, each representing a different aspect of the character. The first piece is a pencil sketch depicting Bucky's original appearance in Captain America 1. The second piece is an ink drawing of the Winter Soldier as seen in Captain America 2.

The third piece, which is the one you're referring to, portrays Captain America and Bucky in a combat pose from Captain America 3: Civil War. It was created using marker pens with alcohol-based colors. Each artwork in the series is framed with classic Marvel comic book panels featuring Bucky. When displayed together, the five pieces can be arranged as a continuous narrative.
