Pink Floyd WIP

Well....I am not sure about this I have been working on and off for a few weeks on this.I got to this point and am not really into it.I need some ideas to finish it.There is alot of empty space on the paper,I originally thought I would put the dark side triangle,and Pigs....the cow maybe.I dunno....help!
Pastels on velour as usual.....I am posting wip's tonight because I cannot seem to finish anything these days.
