This poster I designed upon the "Split contest Shattered Self Contest" published and sponsored by Deviantart and Universal Studios, and judged by DeviantArt Staff and the movie's director M. Night Shyamalan

Concept
I design the poster with the concentrated effect of splitting and chose the broken glass as a strong element to this effect. With some red glitches to give a little blood feeling without harming to watchers' eyes.

Contest Entry
Everyone tries on different personas, behaviors and points of view sometimes leading to internal conflicts—whether it’s tension between what you want to do and what you know is right to do, or between your active side and your lazy side.  But in the movie Split, Kevin (James McAvoy) has internalized 23 distinct personalities—and a 24th is about to be born.  Kevin’s personalities are in constant conflict and fight for control of his body, and the result is a battle for power that drags everyone along for a terrifying ride.
