Well, technically goth-culture (at least modern goth culture) is about emotional pain. This is typified by death, and with that the wearing of black (as is usual for people in mourning). Effectively, goth culture is people who are in mourning all the time. Though not neccessarily because of a person's death.
However, few people realize this, including many so-called goths, who tend to be punk rockers or the like and just like wearing black and "acting goth" without knowing much about it.
*ahem*
That said, the sprites could use some work, and the solid black does not do any sprite well.
