Modeling a Head

I am following a tutorial on modeling a head… I can follow it pretty good and getting to work most of it… but am trying to form the mouth… but now suddenly, when I try to move the vertices, it is not just the mouth that moves, it is the entire head that moves… not sure what I am doing wrong that it is not just moving the mouth… to form it…

here is my file… I’m at right now… I’ve restarted it many times trying to get it to work…

thanks…
the tutorial I’m watching Is Tim - Pt 01 Beginning the Head from YouTube I like the tutorials but for some reason, my vertices aren’t moving to form the mouth like he does… the move the entire chin area… so not sure what I did wrong… I didn’t make my chin as long as he did in the tutorial because am trying for a bit different look for the person… but that shouldn’t affect the vertices moving I don’t think… a couple of restarts, I got mine to move like they should to mold the mouth but mouth didn’t look too good so started over… character.blend (442 KB)

thanks

You have proportional editing tool enabled in connected mode (alt+O to toggle) and it has a big area of influence.


thank you… I was checking his settings in the tutorial and he had it turned on , so I had it turned on… will try without it on
appreciate your reply
