How strict is it about what cosplays you want to shoot at the event? I have cosplays I would like to make for the event, but what if I list them and don't finish in time?

We know plans change, but try to kep it real. For ex. If you know you have like 10% chance of making cosplay before the event, then its a no no, but if you think u can make it but shit happen, then its ok.
