last one looks like it could of been a better tag had you not added a boarder and the text. and maybe some exta colors added in . and i like the first one it's interesting to me but im currious to how it would have looked if the effects u have that the sprite is sitting on be greenish color along with the brown and your light blue? the others didn't really catch my eye but it's a good start on a style your working on for your self.
