Lets put it this way - for a work in progress shot to be acceptable and left unlocked you need the following:
Relevant Information
A few (not just one) screenshots that demonstrate well what's going on so people can comment, even if you attach a demo, people will want to be sure they want to download it first and they rely on both info and clear, good sized screenies - otherwise they most likely won't download, people won't be able to comment on it and then a mod locks it, meaning a waste of time and space for yourself.
Sorry if it sounds picky and demanding, but its done like that for a reason.
