Looks good, but i'll just mention the obvious. You need to get a weapon enchant and you need more hit. Then again, I'm just a hit slut.
Also, any particular reason you have 1/3 TM? If you are going to have any points at all, why not 2/3 so you can at least throw a SS. You could grab 1 point from Imp sunder and throw the remaining point into 2/5 Demo?
