I'm not going to get a lot further with this unless I can start adding some mesh to it. Clicking on Alt still accomplishes nothing, in either Move or Scale.
I don't know if there is a connection (or if it's a bug) but clicking and dragging in select frequently doesn't work, the model fails to turn blue. The 'follow me' command is also very inconsistent when trying to create double-curved shapes such as this. Could anyone perhaps add a nostril or two? And if so tell me how you did it!
