well, you can SEE where I got the leg guard from, (cough, the shoulder, cough) and the cape itself was directy taken from vincent, but the base of the cape was added in kmera after deleting the unwanted part of vincents chest. the shoulder was added and resized, and the proper fingers were deleted, and the claw fingers were added and put into place, and the wing was taken from safer sephiroth, (mtaa) and was then resized.
as for the tape? well, I deleted all but the flat end of the buster sword, vortex coloured it white, (i think it's called that) and then added it the the buster sword and lengthened/shortened when was required. (as well as rotating the tape around the blade)
well, I just reveled the secret of how I threw it together in half a hour for the field, battle and world map. (for the battle model, I just used the copy and paste method.)
EDIT: sorry, didn't see the end of your post. the field models are like fleas dancing around on the battle models body, size wise anyway. and I don't know, but maybe weemus could help you make a more child like FF7 since he did chibi FF7?
