I'm sorry, I'm going to sound like a dick, but 4/10. The colours are nice and the picture isn't half-bad, but there's no flare to it. I feel like if you made it bigger and added some *PAZZAZ* to it, then it'd be at the very LEAST 8/10. Ask around for profile pic editors, I'm sure you'll find one.
However, I DO really like your Persona 4 signature.
