Hello, I am also a fan of kingdom Hearts (as you can tell by my Icon ^^) but I have something that most of the people who enjoyed the Roxas theme would also enjoy. It is the Ventus theme from Birth by Sleep, here is the link.
I played through it once or twice, dosn't really follow any harmonizing chord progression, does it. Still sounds nice, nice step wise motion though. Sounds like something I would have written in a high school music theory class.
Oh. (having played music for year now) AN accent poins up (Like this ^) and an up-bow (like on cellos, violas, violins and upright basses) is like a V. I'm not trying to offend you in any way (srs ._.)
