Thanks! I retried submitting just as you posted, and it worked. Maybe it just takes a little while for Sketchfab / CG Cookie to update and see the model. I’m not a back-end person, so I’m not sure how this works, but it might just be that I need to wait 10-20 minutes after I published the model to have CG Cookie see it.
Thanks for the help! Oh, and thanks for the awesome tutorials. Modelling a face had always been a daunting task for me.
