I like them. The Basch one and the very first one is very good. Oh and the moogle one is cool too. The text is ok in these pictures, but i'd consider using some more exciting text in the future.
ALso you should try more than one colour in the signatures. Rather than have like grey all over, or pink all over. Have like red green and blue, or gold white and silver. Just makes em look cooler.
Im not sure if there are your first signatures or just your first THREAD for signatures. But f theyre your first, they're very good.
