SciFi and Fantasy Art: Snarling Demons

The demon on the left looks well done, except its shoulder should be in the picture aswell, right? and the one on the rights head should be tilted up at the one on the left, since it's not snarline at its belly? ^^ *I TOLD YOU NOT TO GET YOURSELF EATEN!* Anyway, you seemed to have rushed on the right side of the picture--what is that in the background? Ease up when you draw, you seem to shade too darkly and once you do that you are afraid that if you erase then you'll screw it up. You need to sit back every few minutes and take a look at your picture while your doing it to see if you like it or not. Oh crap I need to stop writeing! Bye!
