1-minute human ear topology with 5 extrusions

Hi everyone!
This is a simple solution for quickly modeling the ear with just 5 extrusions (!)
I know the technique is not perfect, but may be fun, and even useful for some studying.
Maybe with help of others we can get there.

OBS.: please note that on this tutorial I didn’t pay attention to getting the shapes right (in part so that the steps become more obvious and explicit) this is your job as artist! (If you don’t know the anatomy of the ear, i recommend PROKO, the Youtube Channel of Stan Prokopenko)

I apreciate criticism, this is as far as I could go by myself so far!
Thanks in advance
