Its a good concept. It could use some refining tho. Since its robotic, try to make everything nice and crisp. Smooth lines, not brush strokes. At least not on something as simple as this. The mapping is a bit off too. Remember that as you approach the top of the texture, you need to draw wider marks to keep the width the same when it goes on the head. From the spinny it looks like it narrows to a point on the top.

Also, I can't tell which side is the front ._.

It just looks unfinished, like a concept instead of a finished texture.

5/10 for good idea, +1 for first robo head, -1 for unfinished look.

keep at it!

Right now, these are just panels. I'm not sure what you tried to do with those wispy-like lines, but they do not give a robotic feel. If your working in 512x512 the work tends to be more detailed, if there isn't as much detail, it will look very basic. And as you know, robots are intricate. Even try using metallic looking gradients. Right now it's "eh". Use a reference picture next time.
