Humanoid Robot Character Research

For our Game Art & Machinima project, I've chosen to create a humanoid robot character and it's Archetype falls under 'Villain'. After creating my first draft of the Robot, I received some criticism during one of the interim Crit sessions. It was brought to my attention that my character looked too much like the 'Iron Giant', therefore I had to work on another idea. Revising back to the criticism I noticed there were a few similarities, I guess I drew the character with the Iron Giant in my subconscious.

Above (figure 1) is my idea of the robot redrawn by my group member Jess, the Robot has similarities to Iron Giant.

Figure 2 is the Iron Giant.

-I then begun re-researching to get inspiration for new ideas by looking at illustration of Humanoid androids online.

-Although my new idea was sort of straying off the 'humanoid' angle, the idea was to have a head for a body and it's arms and legs connected directly to the head. I did some research of 3D android illustrations to help me execute my plan. Below are a few Ideas and inspirations which caught my eye.
