I recently finished three custom busts, that will be part of a full X-men Marauders villain team set in the end.
Arclight is a Battlestar Galactica: Kara "Starbuck" Thrace bust, with 3D printed crater base and rubble.
Riptide is a Bowen Kazar Bust, minus Zabu, with a 3D printed base, and hand sculpted powers.
Greycrow/Scalphunter is a 3D print of a Conan the Barbarian bust, that I digitally edited to remove his necklace and added a new base. I used Star Wars Deathstar panels, also 3D printed, to make his techno-armor. Each one is individually placed.
