It's okay, not a lot of people do.
This link should explain it (warning for foul language); Sovereign Slayer is one of the titles used by the character Jack Noir in
Homestuck, and the banner depicts him in one of his more psychotic moments.
For yours,
level99love: My major complaint here is the huge amount of blank space. The blank line between the two images could be removed, and possibly the images could be coalesced into single images to help with centering the banners. Otherwise it looks awkward. Despite that, the rainbow sprites, though some may not like them, make me nostalgic, so I'll give you a
6.5/10. A lot of it's probably just me being an old fogey, though.
e:
Pamizard: The colors of the text and the banner don't match, but they look nice together. Even though I'm not a fan of Naruto, I do like how the banner looks. So I'll give you a
7/10 in general and note that my scoring is simultaneously erratic and stiff.
