Yeah I got the head-twisty thing too first time out. Luckily I saved right before so I was able to try again with better results.
Oh, I meant to say something else about the hair in ME3. This may just be me, but in some scenes (most notably in Javik's quarters) it goes totally transparent. I figure there's something screwy with the graphics engine as the room has that smoky looking atmospheric effect. Shaders overlapping perhaps?
