hmmm bg is simple, looks like u just did a riple filter on a blue bg, i dont find font going to well with that pic...and my number 1 rule....if the sig doesnt blend in well with the forum/site/whatever bg...allways use a border (but thats just my oppinion, looks better)
So my suggestions are for you, try learning how to brush, thats how i finanly became "a bit" better *points at my sig* (third brush sig...ohwell), try finding better suiting fonts and maybe use borders...
but overall i think its quite good for a second sig...6/10
