Why do you get bright/flashy colours? Can't you pick out decent colours?
The colour flow is very important in your signatures, if you don't get good colours then it ruins the signature completely, like this one. Blue, Yellow, Sky Blue, Purple, Red, off-white? There is no colour flow AT ALL which ruins the signature completely. And just take a look at the Test picture, floating on the top of the background making the 'tag' look even worse.. text is ok, nothing special really and it has it's own flaws.
I won't be going easy on you. Honestly speaking.... this is completely awful, 1/10.
