Well, as for ff7music, you need version 1.15 of ficedulla.dll if i recall correctly, NOT the latest one.
As for this, photoshop probably wouldnt be of much use, becasue allt he cahracters in the game are msotyl vertex shaded; aso, full modesl aren't made by themselves, they're actually a colelction of parts (So teh head is a different model from the torso, which is different form the shoulders, which is different from the...) But if you can do that kind of thing, make up an npc model and show everyone what you can do, and i'm sure borde or reunion will intergrate your work =)
