Robot concept sketches, GO FOR THE FACE

So after all of the character development research I conducted this week I finally sat down sketched some facial expressions on different character sheets.

To begin with I looked at my initial idea and what the flaws
were with the design. After that I began to sketch
different designs and listed their pros and cons.

After some ideas i decided to stick with the complex design
as it had more facial features to show emotion.

After finishing the last of the face reactions I looked at
minimal ideas like Wall E and created a rough idea
of a simple concept.

The concept was designed like the human face but with
a more robotic feel than the previous ones.
