Hello,
I give you my opinion, but without offense or doubtful criticism, just an evidence that you must correct.
No decription
No wireframe, just few very simple render for very simple model
Just need 30 mn to do the same (10 mn for the hat with a lathe modifier with 3D Studio MAx )
it's just a begin you still have to make a lot of progress to make significant sales
Good luck and happy new year 2018
