I noticed your avatar and said "I might as well try again at Sprite Sigs". (Note: This is only my second Sprite sig, so I don't really know all the elements of working with Sprites.)
For a second sprite, it looks really nice~ The only thing I have a bit of a problem with the text. It's just really "Neh" to me. Maybe because it gets blurred at 'mood' and it gets away from the sharpness of the signature. Good Job, though.
