kinda looks like toki from dethklok, really, it looks a lot like that art style.

if I'm right think about who you're talking about, I don't see the general features of the drawing style. I adhere to semirealism (I mean the style of anatomy is not quite like the cartoons and not a flat shades), and the character (Toki) is drawn with flat shadows, with visible black lineart. and the similarity of the characters I also do not see. they just have long blrown hair and blue eyes. hairstyles are different, facial features too (the type of nose, a cut and eye shape, face shape and chin) and this is not a boy, it's a girl (in this picture she is 15). I myself have blue eyes and long brown hair and usually my friends compare Lavi with me and ask if I drew myself in younger age. so your comparison is very unusual to me
