Hello, I'm fairly new to Blender, and this is my first post in this forum, so..... please go easy on me...  ^^;;

I loosely followed this tutorial to create my half-head.  (I don't want to make it a whole head until I finish tweaking the half to my liking...)  Now, I did some editing of the edges and vertices (nothing new) only this time, when it rendered, the edges look really sharp and faceted.  I have the half-face object on 'set smooth' and some of it renders smooth, while other parts render sharp.  I don't know why it does this.   D:

Here is how my half-face looks in different views.

So, I guess my question is; what is going wrong?
