David Horde was just your average junior college student stressing about midterms. That is, until he was bitten. Zombies in his world are a lot like vampires. Not really an apocalypse situation, and more of a secret group of monsters in hiding. As the star of the basketball team, David had a rival that was particularly jealous of his abilities. So, naturally, he tracked down a zombie to get rid of him for good. David now has to navigate an entirely new world, and a new (after)life with a group of people who ruined his chances of living normally. 

In this situation, David is with his new zombie peers who are teaching him their favorite dance- the monster mash! However, David was never much of a dancer. The guy is very tall and has two left feet, so when it comes to parties, he's more of a snack table guy than a dance floor one. Because of this, he's finding the choreography very confusing. He's trying to remember it all, but it's quite the challenge for him. Luckily, David is not the type to give up when things are hard, and when things like this are thrown at him, he hyper focuses on getting it done. After all, he has to get used to being a zombie. 
The most visually important parts of this pose would be the exaggerated body movements, pushing this idea of complexity within the dance. His face holds a perpetual raised eyebrow to show that he has no idea what he's doing. (But maybe he'll figure it out one day!)
