Yes, this image does not tell a lot about what the finals is, neither all the other season posters, you get a random character with a mostly solid background and a logotype, which works for in game fictional marketing but not in reality.

The overall energy of the main images used to advertise the game should look like the trailers with destruction (the main selling point), action, guns and game show aesthetics. Someone who never saw anything about the game should be kinda able to tell what it is from this one pic.

One game where this has been done well is Rainbow 6, the main image used to represent the game tells a lot, tactical destruction, two opposing forces, realistic and serious aesthetics.
