Not actually based on a real Iron Man armor, but I thought it would be cool to have a medieval version of ol' Shellhead.  This bad boy was made entirely from a Hasbro Marvel Legends Black Knight figure.  The bottom of his mask was sculpted in Aves Apoxie sculpt.  I also embedded a rare earth magnet in his left forearm to that his shield attaches magnetically to prevent paint damage from equipping and removing the shield.  The whole thing was basecoated in black before being drybrushed with armored steel.  The metallics were done by painting clear red and yellow over the armored steel.
