Don't mind him, he seems to like to pick fights with people a lot from what I can see.

I may be an easy-grader, but I start everyone with 10/10 and then subtract points for mistakes. Now then:

Very nice! One question though...what is the japanese lettering in the corners?

As a stand-alone, I see nothing wrong with them and they are actually quite nice, easy on the eyes, and pretty cool looking. I'm gonna give you a 9/10...if the japanese lettering actually means something then revise that to a 10/10 but if you don't know what it is then 9/10 because it really doesn't obstruct the rest of the image.

My opinion is by no means professional, but I do SOME graphic design myself...mainly spriting. I say good job!
