I guess the difference is where you draw the line on homage. Both pieces are clearly inspired by, and are meant to be a reference to the Wick image. Absolutely nothing wrong with that. The difference is, the first artist went off and drew their own interpretation of the idea. The second looks like they practically traced the Wick art.I'm not sure why that matters. If it's a clear homage to John Wick (which this is; I recognized that immediately when I saw it), keeping the same construction makes sense. No one is trying to pass this off as an original concept.
Also, John Wick didn't invent this concept, though they might be the first to put it on promotional material. With two minutes of googling, I was able to find several images of an isolated protagonist facing the camera, surrounded by faceless hostiles brandishing weapons, which predate the John Wick image.
(Note, I don't know that's what the artist did. But that's the way it sure looks).
It's up to you whether that bothers you or not.
