To make it robotic you got to have more than just the visor :P

i know i just want to know how to make it more look robotic

add more detail

ok looks kind of too havy(it is really hard for me to drawing robots because im a beginner)

I like the second one better.

Drifting to more offtopic:

Your avatar is really bad. Cropping is horrible and that consistent copy paste Plasma cloud filter. I have better cropping tips.

yes youre right my avatar sucks and the robot sucks kind of too but i have no ideas too make it look better
