And I wanted to make a Rhino

So far I've gotten. BUT when Im trying to convert the polygon to a subdiv the script editor says
"Nonmanifold geometry cannot be converted to a subdivision surface"
I figured out where the Nonmanifold geometry could be,
using the `Cleanup tool´instead of cleaning up I just choosed the "Select Nonmanifold geometry".
And here they are...

What shall I do now?
Btw: May I upload pictures of Maya, When Im using Maya Persornal learning editon?
