This is my first post here, and well, frankly the work so far is beautiful and you all deserve a good pat on the back! But before I start waffling on with praise I felt I had a suggestion which I am not sure if it has been mentioned before, but it is to do with the Background art that is being done by many modders here.
Back in the day I used to mod Warcraft 3 and was rather successful for a time, but a key factor that eventually led to the mod I had collapsing was a lack of consistant knowledge about what is needed to be done, and unfortunately I have noticed this in regards to the Background Art and so my suggestion is this:
My suggestion would be to add a new stickied Thread which has an image of every single background on it that is needed to be done (either for the first "demo" release, first disk or full games worth, lets go with the name "To-Do Backgrounds"), when one of the backgrounds is remade it would be deleted from the "To-Do Backgrounds" thread but appear in another stickied thread that contains all the finished backgrounds done thus far. A further improvement would be to allow people to respond to the To-Do Backgrounds thread to let people know if they are working on a specific background, and the original post can be updated to include lists of those working upon a specific background, this would enable people who are not currently on the team to know what is needed to be done and what is being worked upon, and may actually encourage more people to discover a background and give it a go. Also having a consistant resolution to have renders saved at mentioned in the threat would help bring some consistancy to what people are making, as I have noticed some confusion over what resolution is currently being required by the team.
I do understand that such a pair of threads would actually be an incredibly demanding piece of work to make at first, considering there are something like 700 backgrounds in total and just hosting them up will take a great deal of time, but I do feel that currently things seem somewhat higgly-de-piggly-de at the moment and very confusing to know what you can do. I personally would like to get involved, but do not have the PC version of Final Fantasy 7 only the PSN, and such a thread would easily allow me and others like me to dive in and help you out.
Sorry for waffling on, and I hope this suggestion is taken well, as I mean it with the very best of intentions.
Edit: Truth be told, something like this would work really well for which Ingame Models need to be done/have been done (such as Character Models, Weapons, Foes) but also for Battlefield Backgrounds too.
