jakebb44, find a nature.jpg you like, for reflections - and put it in the same folder with the POV file.

Snarr... About the neck joint texture, I'll add it tomorrow.
About the 360 rotation... I've been thinking about it all the time
One option is to change
#declare leftright = 30;
to
#declare leftright = 180;
and, to disable up-down rotations, change
#declare udspeed = 4;
to
#declare udspeed = 0;
Finally, if you want the front of the head to stay longer, instead of the back...
#declare lrphase = 180;
But this will not do a regular 360 rotation. It will still do a swing. To do a regular 360 rotation, instead of the changes I suggested, you will have to change other 2 things in the code, below the normal stuff.
There are two places that the following appears:
rotate <
arphase + around*sin(arspeed*pi*clock),
lrphase + leftright*sin(lrspeed*pi*clock),
udphase + updown*sin(udspeed*pi*clock)
>
You will need to change them to
rotate <
arphase + around*sin(arspeed*pi*clock),
360*clock,
udphase + updown*sin(udspeed*pi*clock)
>
and you'll get one regular 360-around rotation. A bit complicated, and I plan to simplify this in later versions.
