the shape of the ring seemed kinda like clouds Fenrir crest on his left shoulder
something i really liked, i think it's open for interpretation:
fenrir, or the wolf
a wolf kinda symbolises a strong sense of independance, but often you see a wolf running with a PACK
Cloud kinda reminded me of a leading/independant "wolf" who didn't have his pack in the beginning of the movie
but as the gang rejoined, it made him complete
the movie had so many great moments, you all named them all :/ lol
EDIT
When cloud is talking to vincent and cloud asks "can sin be forgiven?"
he replies "i've never tried it"
Cloud then seems determined to try
in a physical form...bahamut SIN came and he had to conquer it...not alone either
see, i love symbolism as you can tell...it may not have been the original intent of the movie makers but it doesn't stop me
EDIT TWO
Cid still has his goofy run! After he saves Tifa, he runs off with that wierd strut and his arms close to his hips...HILARIOUS!
