(somewhat off-topic) gaara-kun and sakuma, considering that you are both relatively new at making sigs, you guys go off on everyone's stuff, telling them that it is horrible. If he likes that style, then let him be, crits doesnt mean tell him to change it so you like it, and it suits your style. Just tell him if there are any things that really stick out that he could improve like low quality pics or something.
now that I am done with that, its a pretty nice sig, try making a black border around the outside edge tho, that will make it look a bit sharper. Keep up the good work
