This model was created by following Kent Trammell’s CGCookie tutorial introduction to Blender 2.8. (https://cgcookie.com/tutorial/modeling-an-ornamental-shield-with-blender-2-8)
I had to import the model into 2.79 and convert the curves to meshes there, before uploading the file to Sketchfab, because of the current limitations of the 2.8 alpha release. That's the reason some of the ornamentation doesn't sit quite as nicely on the front of the shield as it could.
@theluthier Thanks.
Fantastic result 👏
