ok i was trying some new things with the robot style and here is the result...CnC (yes i am aware their's a line in the back...will fix later also the circles arent perfect because i forgot to use the circle select tool on em...i can also fix that)
nice but i think its too empty...you can fill in the dark gray parts with some more red
i like the "circle".. but the B...
the back of head is great and the front top also!
