Redline help?

I am trying to make my first fur suit. I am a very long time lurker but never had the guts to try making a suit before.I am trying for a dog, just a general mut. I don't have any concept art because I can't draw. I made this using Matrices tutorial. Any help would be super. I have adjusted one side of the muzzle, I noticed it was a slightly longer size. Also how to make it smile?

Thanks
