I like the Sora one:)
lol you're probably just having sig maker's block, just try and make sigs of different things. Like something you haven't tried before or try something new with old subjects like KH2 or Naruto. Oh and I like your new one good job.
Try to avoid render stacking...I mean this BG is good but the stacking of Kairi on Sora isn't nice...
想要對妳說的 不敢說的愛
sora is stretched =/ instead of making kairi see-through, maybe blend the two images together.
running out of ideas? hm.. try making some sigs out of final fantasy or real people
