This is just a rough sketch of a design I'd imagine them giving Liu Kang for a lower budget, "modern" look. I went for a basic tank top and black slacks like the movie, but I really wanted to add some red trim, so I added a patterned strip to his pant legs and a red gem with some beads around his neck in lieu of the headband. I took inspiration from some rumors about the new movie, with the gem essentially serving as his ticket into the tournament.
This is no masterpiece, but it was fun to think up. I might do an edit to this to make one more like the games, which would be my ideal depiction of Liu Kang.
