Just printed the Bust. It came out with some minor issues. Primed it and painted. I am not great at painting as you can see... anyways I really enjoyed to make this. If you try to print it let me know how it turned out.

I used a refernce pic of the negative man of the tv show doom patrol and used this two models:

to make the negative man bust. I used meshmixer and sculpted the models to get negative man.
