As SithLord said, I don't see anything wrong with your thread, but there's always a few things to consider. I'm not an expert, you don't have to trust my opinions, and it is your thread at the end of the day. :>
If you're constantly getting hits on the same idea or story when you update your thread, as you seem to be, remove it. People can't request it if it isn't there, and you can always add it back in later. It may lead to less messages, but you aren't taking people up on that idea anymore so does that ultimately matter?
The information under the images you have I'd say would be better off in an O&O thread, which you can link to in your request thread. The General Info part is good, though, and should stay.
I would lay it out as following:
General Info
Plot Ideas
Pic inspirations
Parings
Again, just little tweaks which may or may not help in the end. Overall I find it takes a considerable time to get your thread perfect and to the point where you go 'Yes, this says ME.'
I hope that helps some. :>
