Its not the legs its the entire posture of the knight. He is standing stight up like Mr. Belvedere and should be holding a tray not swords. It's conflicting with the design, which is fucking awsome. He looks too friendly/vulnerable/nerdy standing like that. After you finish designing the leg armor I say you stick with the design but redo the entire picture and make him look more aggressive by giving him a tilt like he's coming to get me or he's not gonna let me get by.
Strange coincidence that every man whose skull has been opened had a brain.
