Hrm, not entirely grunge, the colors and such, plus that brush-like image in the middle isnt grunge. If you have crystals etc, and other trendy stuff, its not grunge, because grunge isnt trendy.
But I really like that sig, its a good change for once in the look-wise department, even though its the same style. What's nice about your images, is they are refreshing each time I see them.
