You aren't supposed to start just yet- not until November 1. Not that I care since it's almost November, and I forget whether you can still post excerpts of your novel on your NaNoWriMo profile. In any case I wouldn't ask for criticism while writing. Even a really good writer is going to be churning out stuff that's VERY raw, especially around the midpoint, and getting discouraged about the quality won't help. Once you're done, I'd let it sit a while, give the whole thing a run through for editing, adding, deleting, changing, etc., and only then let somebody else look at it.
