I just watched iron man last week and the special effects really amazed me. Iron man's design is also great that's why I tried to make a 3D model. I didn't have much reference so I just tried remembering what I saw.

This model is a bit on the low poly side. It's not really exactly the same with the one in the film but it's close. You can clearly see the edges where it should be smooth. I'll try to make a better one next time.

Trivia: In the film, Stan Lee makes a cameo. He is the guy Tony Stark(Ironman) mistakes for Hugh Hefner. Also, the director of the film Jon Favreau is on of Tony's bodyguards.
