I can't really explain the picture, b/c it is of little importance. The main thing I was working on was perfecting Rexar, (shadings, body structure, etc). I made this for  RipRoarRex for being a fricken awesome artist and one of my personal favorite.

Hey, I didn't use gimp for this :3
Oh wait, yes I did....just for the background since white is such a plain colour.

in case you are wondering, those are Rexar's socks that he is teasing Lu with. LOL like I said, there really wasn't a story behind why I wanted to draw it like this.
