These are my Brickheadz of Captain Kirk and Mr Spock from Star Trek. I have tried to stay as close as possible to both the look of the characters and the official Brickheadz, except for the eyes which are not currently available in LDD.
If you would like to build them, the instructions are available at https://rebrickable.com/mocs/MOC-14988/MICHAEL1/kirk-and-spock/
Thank you for looking, any comments or questions welcome!
