This Age of Ultron: Ultron Prime is an excellent custom minifigure with some really nice sculpted pieces, including the head and amour which has been crafted onto a LEGO skeleton body. The extended calf muscles are a great touch and some Neodymium magnets hold the legs in place.
The paint work is of a high quality on this minifigure with some nice red highlighting, and it has been sprayed with gloss sealer to complete the look.
Overall great work on the Ultron Prime and a very nice photograph to showcase this minifigure.
