its coming along very nicely, i'd definately finish it if i were you. I like the way that the outer edge is thicker, involving the viewer, well done on that, if u finished it nicely, and did a nice CG, it'd be sweet. Im not sure if the eye's are intentionaly different sizes and the contor that touches the eyes looks a little off if its ment to be a full circle, but this is subject to what you are going for. The only problem i see is the half finished leg looks slightly angled, maybe it would work im not sure, i dont know what the hips are like on the robot >_<. I wanna see it finished :]
