Firstly, I don't own the copyright to the original Iron Man marketing material.
However, the original Iron Man marketing did inspire me to make this promo, just as a test of my capabilities. It isn't for any client, I just wanted to see what I could do with it for my portfolio.
The reason I tried to replicate an already existing promo is because it helps to recognise the subtleties behind it and to realise that all the little things combine to make a more realistic result. For example, the blemishes and scratches on Iron Mans suit add a real sense of depth to his appearance, using the correct lighting is also as important to emphasise these details.
