The way it works right now is that only required documents related to the assignment count. As long as the required ones are found and photos are taken, you will get a positive response. I do want to have some mechanics that penalize you for taking poor quality photos, but have not implemented them yet.
It is definitely not a long game, and probably never will be, but I wanted to make sure I got something online. As for suggestions, comments, sure, anything is fine.
