Retro scifi bounty hunter bust

Im working on a retro scifi alien bust. The idea is a bounty hunter with a classic xray gun :D
The overall height will be 8cm (top eyes to belt)

First rendering, finding all the main shapes

I decided to go with wider shoulder pads to make the overall triangle design more pronounced.

More details and I opened the mouth to make the face more visible.

I started to play with posing ideas
