I'd say the tutorial was either a really bad one, or you haven't followed it properly.
The first thing you need to work out when drawing manga is the face proportions, eyes are always in the middle of the skull, ears are always next to the eyes etc. etc. I mean, it's incredibly incorrect proportion wise, the eyes aren't even in line with each other.
He's also either missing an ear, or the little bump near his nose is the other one, if so, ears are adjacent to each other o_____o
