This is one of those character designs that was less a series of conscious decisions and more something that just popped into my head and said "DRAW ME"
And I can't shake the feeling that he looks like someone. Some long forgotten anime character...I know at the very least, I got that hairstyle from somewhere; because it's not really the kind of thing I like to draw.
My top suspicions are:
I've never actually watched either show, but I've had a lot of exposure to the characters. Maybe one of 'em rubbed off on me subconsciously...
