This is my first 3D project.

I started off with 3 consecutive circles on top of 3 consecutive squares. A cheeky little copy and paste into photoshop 3D as a smart object. Deleted the white and extruded to a new 3D Layer. 

I played around with a few preset extrusions and really liked the look of this one.

It reminds me of a fly's eyes. 

I added some pearly whites. 

I added a postcard background with a single color to set the mood, a bit of hair made if metal rods and a chin. 

I decided to add a simple mandala background to finish it off ... and voilà - my first photoshop 3D project,
