Ironman Final.....(possibly)

This piece, based on my experience and knowledge, demonstrates the most important aspects of a good portrait. The first is the shading quality, which is particularly prevalent on the sides of Stark's face, his facial hair and his Iron Man suit. Another is the realistic appearance of his eyes, such as the faint highlight in his iris, the shadow around the far corners and the inside of his eyelids. Above all else, I can easily see the wrinkles and creases on the face of his skin, particularly those around his nose, the sides and underneath his eyes and his cheekbones. To finish it all off, you've added a dark blue background and added a faint blue edge light around him.

Wonderful work
