I used a DCU Superman for the base and sculpted the shoulder pads, boots and used cut vinyl for the bracelets. The collar is a rubber ring painted white. Click on the image to see a larger version.
I used an Earth-2 Robin figure for my base and Secret Origins Bruce Wayne head. The boots are cut vinyl and resin as are the gloves and shirt. The stars are custom decals that I printed on my Epson using decal paper.
I used a DC Universe Superman Blue for the base and sculpted the gloves, boots and mask. The belt is a cut piece of vinyl with a resin seam in the back.
