This Firefly Arkham Origins custom minifigure looks excellent and the sculpted pieces on the legs, torso, arms and propeller bits are made from a sculpting air dry material called Greenstuff.
The wings which really stand-out are modified LEGO 1 by 4 grey flat pieces which have been cut, trimmed and sanded all over.
Finally, the minifig has then been painted. The yellow and grey are a great combination on the wings and the orange visor and shading on the helmet is very nice.
So overall a great job of sculpting and painting!
