Hah! I remember way back when you made a drawing that was some kind of portal-like robot, that I thought you had a lot of potential. You drew good, but that it could be even better. And now I look at this! This is awesome, it really is!
My only nitpick would be to use a texture with a higher definition for the background, but to be honest I am bad with textures as well, so it's cool! Keep going.
