If you put that globe thing over the little robot dude and blurred it, you could have some pretty cool looking depth, just all looks a bit kinda random to me at the moment lol, maybe make the robot guy bigger, considering the size of your canvas.
I think the globe thing looks like a bubble, So I can see where you were going with this one but it just looks like you either did not finish it or you gave up I think you should stick with your usual style for now thou. However its alwasy nice to see somebody experimenting a bit with new things.
