ok, for the first sig (of your last post), it looks great! but I think the at left-bottom corner it's kinda too blurry looking, I don't know how to put it, but it just don't match well. I think it's just me though, ^_^;; so don't need to worry about it lol
second sig: I love this one the most! the girl (forgot her name) looks so cute! the background looks great also ^^ I like the bottom of the sig, it lkinda ooks like she is smelling the scent lol, keep it up!
