What is that creature? I looked very hard, but i haven't managed to figure this out. Besides that it looks quite simple... A textured plane and then a simple character model in front of it, and the shadow might as well be done with photoshop. If you are just beginning than this is quite good. Otherwise, you should consider Actually modeling the background and detailing the creature, add some wrinkles or something, maybe shade it so that it would look slimy (shiny).
