I guess this might be my 2nd entry, for this contest >>>
The female main character in a bluish theme clothes.
The costume design concept is based on water-like element badge design displayed on the contest main page. Part of the badge is edited coz it is initially overlapped by other badge.
The idea about custom costumes is that they can be unlockable after succeeding using the power of a specific badge, OR they can just be simply available in a story re-play mode. This is one of the thing I can forseen if there is extended/additional special features from the original game title; like "Kingdom Hearts: Final Mix".
Elements are supposedly arranged by number, number 01 is reserved for original costume design.
*Edit: *Edit: Fail liao. Let it be reminded to myself that more self-evaluation should come.
