Happy
Nice work. I think the use of big squares for eyes was a nice touch and gave this character a personality of its own and depth to something we see as an ordinary robot. I love the use of a background light on this and how much you kept this piece of work unique to the work you've been doing and not a basic robot vector artwork. The outline of your robot match well to the color theme you've got going on and you've allow a nice flow of the piece by thinking about consistentcy. I do love this and I think this is your first submission so good job for a first time.
~~THINGS TO IMPROVE ON~~
My only crtique here is maybe add a border with some deep reds in there or yellows.
