Trying to remember the name of the movie with Ally Sheedy and the robot on tracks... This reminds me of him. Technically, not that great but oh, what a whimsical mood it strikes. 8.
On camera flash gives nice eyes but very unappealing lighting otherwise. Your sky has a bit of noise going on in it that could be dealt with better, and seems to be underexposed. Consider a stop or so increase for the shutter.
I like the flash bounced of the "eyes". It gives this "robot" a powered on feel. (Like it is alive!) The only piece of criticism I can think to say is that I feel the foreground is not too much lighter than the background which makes it not stand out so much.
