Hi, this is my first robotic style head. I know it's not very good so could I please have some tips, advice and possible improvements. Also, could you rate it 1-10.

I like the design, but you could use some more shading/lighting.
6/10 for the design, add some more professional shading and it could be a 8/10

Hmmm, It's pretty awsome

5/10 for design
7/10 for the shade's and stuff
