You look pretty passable to me. It's not easy to tell from the pics but it does appear you have a prominent throat, how large is your Adam's Apple? That could be a problem if it is too big. As always though, passing is as much about presentation and confidence as it is about "looks". (Which you've kind of realised with the shaving comment, obviously you won't pass too well with a beard shadow, for example.)
You might also want to try the main "Could I pass?" thread.
