I hope you don't take offence as i know some people take their work very personally. It's great but i don't love it. My problem just lies with the setting. It's strange seeing the Galaxy mario jumping in his regular mushroom kingdom back drop it just seems a little out of place. Same goes with the text. I'm not going to say its bad though because it is a good signature.
If you wanna take a few days thats fine there is no rush what so ever
