So, I remixed my own part https://www.thingiverse.com/thing:4594961  to reduce the design to just the heads. 

It makes the overall design more round/orb like. I think it also makes it more alien. Most sculptures of people include at least the shoulders with the head. Using just the head is wrong unless you are just showing a skull and then it is ok.

I do not have gold filament so I used Blender to render the model in both Gold and Silver. 

I printed it at 50% scale, so not all the details is there. It is about 2 inches tall at 50%.
