Error uploading Blender character to Mixamo

I'm a student that just created my first character in Blender. I want to upload my character in Mixamo to animate it. I exported it as a OBJ file and FBX file but I kept getting errors by uploading my character to mixamo. I read some posts on the commuity forums which allowed me to tweak my character and uploaded it to mixamo. However, she's missing her face and hair. Does anyone have any suggestions, I have included my blender file and screenshots. 

This is what my character looks like in blender 

This is what happens when i insert my character into mixamo.

I have uploaded my character to google drive.

Thank you.
