Awesome! I like the creature design but your shadow seems to be off. Judging from where the light is coming in on the picture the shadow should be cast down somewhere in front of the creature, not behind it. It also seems like the tail of the ground shadow is swinging in the opposite of the actual creature above the shadow. Of course, all of this might not even be true and that shadow might be from another creature flying somewhere behind and above the one I originally thought was the monster casting the shadow. But even then, It would have to be a pretty big monster to cast a shadow that size from such a high distance.
