Ok so i saw the other one and since this one was simular thought i would review this one aswell, but anyways this one is a more realistic one, and its a black backround this time better then the latest one that had just white, Now it could be much better presented with something like a city backdrop or a chatic disator city scenes, even some other robot like characters or maybe just some planet scene, just an idea to work with for the next one, Now i do like what you have here this one looks more realistic and seems like you put a good amount of effort into this one aswell. so after seeing and reviewing two pieces of your artwork it has been a pleasure, but before i go a few more tips might help, on this face part seems like you have those lines again are those tears?? if not it might be interesting if you showed some, and i would suggest ad some "COLOR" in the mix of all this shiny metal, and one last thing would be to have the "FONT" more fancy style, anyways nice job from what i seen.
~~THINGS TO IMPROVE ON~~
A few things like some added color, some fancier font/text and some backround scenes would be nice
