the two labels are so small and unreadable that they add nothing to the head
would've been better to have added scarring and other defects on it instead
if you are going to make the lines go over the head at least make them straight over, on the top of the head they make a v towards the center. (without shaders)
the back looks really horizontal and boring, as this is the part most multiplayer players will be looking at it kinda is meh.. although if you did add something back there you would kinda have to redo the whole back so I'm not sure what i would do in that situation.(personal preferences)
Circles on the ear position are a little overdone in robotic textures because its such an easy addition. But ingame it almost seems as if your angles on the face are fighting with that perfect circle on the side. As everything is sharp while the only other "circular" thing would be the blue paint.
shading seems a liiiiitle confused in places where you may have lost a bit of potential depth.
but its a really clean texture
i like the technique on the orange glow (stealing now)
welcome back to textures. (hopefully?)
