Woah, now that you placed a shadow underneath the robot's legs..the stance makes sense now. The new colors looks great too.
Okay one last thing, I think the other arm should be shortened and legs <like the one I edited with the blue line> by few pixels and put a little bump in the end <circular shoulder?>

Anyway, great job as always Fool.
-Edit-
Okay, from the original image that was posted, I notice that the right side of the robot's seems longer and bigger <arms and legs>. But it should be the other way around. The side facing us should be bigger in emphasis <from the 2 point perspective>
Now if you are using isometric view as a guideline they should at least have an equal length. This is just my observation. I hope somebody with more technical knowledge will explain this further or correct me if I'm wrong.
