This is why being untrained and inexperience is a problem if you intend to try to do work that once in a saner world they ask a full timer to do.
Dude you own a DSLR how hard is it to get 3 people to give you 1 hour of their time to test it out. This is how full timers learn before they go an take a job in an area they are not experienced in. Best understand what kind of group photo they are wanting.
I have this winnie the pooh soft toy that has been my model for so many occasion
Want to get back to photography
