The XFC likes to feature ALL of their fighters on event posters, including undercard competitors. This is great for the fighters and shows the XFC' dedication to them, but it also makes the poster design a bit more challenging. More of the design space you would normally have to play around with when creating other fight posters is lost due to the number of people that have to be fit into the small space.
For example, there are 24 fighters featured on the poster above, in addition to the event details, sponsor logos and organization logo. This makes the design challenging, but fun, as it then becomes almost matter of creating a "crowd of fighters" who are going to make the event worth watching (from a marketing standpoint).
However many fighters need to go on the poster, we are happy to accept the task, and we hope to continue getting better with each poster.
