Self Portrait as machine

For my first graphical assignment I tried to include many different characteristics and references to myself and my life in the portrait, you probably won't recognize all of them unless you know me really well.

The machine's face is very human in shape and actually resembles the outlines of myself. The same goes for the proportions, eyes and eyebrows are dominating in both my real picture and in the machine.
Other things are more subtle, all the "materials" used have some significance for me. I decided not to stick to one theme, but used different raw materials for the collage, ranging from cameras to fry pans to bicycle gears.
