Too flat. A sword usually has a double shade. Half light, half dark. 2/3 of your sword is light while 1/3 is light. There is no glare whatsoever to the sword and that IS necessary when it's a sword. Unless if it's a different material. Also, ice has a different texture than metal, so it'll be hard to shade that. Frankly, it will have to be a bit "transparent" and lots of glare due to the fact that ice has a lot of light coming through.
