Looks odd because it suffers from crooked lines syndrome. A common mistake newcomers make when trying to draw something that they are copying. If the same person tries to make something original, it gets far weirder and crookeder.
Good attempt, but I feel you should have spent more time in keeping the lines from being all crooked and incorrect. The main shape is correct, but that is about where the "correct" part ends.
Also, try not to just directly copy pictures. You only want to do this very rarely, and I would suggest to do it with something that is real, and not already drawn, that way it teaches you more about how things should look anyway (if you can't get something that was real drawn in your style, then you will do far worse for something that is already fake). Never directly copy a picture somebody else drew unless you POST the original along with yours and explain that you were doing so (you at least got the latter part correct). This way you don't come off as a wannabe art thief.
Also keep in mind that you get 0 credit for copying, and heavy referencing you get only partial credit at best. Basically, you only get credit for what you originally made. Don't expect to get credit for anything BUT that.
Anyway, just keep trying.
