This Bounty Hunter Custom Minifigure looks excellent and is a combination of three third party LEGO custom vendors.
The minifigure is the high quality digitally printed Head Hunter by Brick Moc which features a 360 degree design and arm printing. The painted orange hair piece is by eclipseGrafx from his Kid Flash custom minifigure along with the printed HUD. The HUD mini build is a great idea!
Finally, he is carrying the Offensive Combat Peregrine SMG by BrickArms along with the LEGO Star Wars helmet.
Overall, ExoBrick has turn a very good minifigure into an amazing one with these combinations – well done!
