Damn Max, you and I had the exact idea for the robed person in the middle of our weapons and you beat me to the post. I was sketching up ideas last night during work, and should be able to post them up later on today once I get to sketch them out in Photoshop.
Ok, aside from my complaining ^_^, the only thing I can add to what others have said is that I fail to see how the angelic hammer is a hammer. It looks more like an axe to me with all the curved edges, but I also agree with Goraaz in that it looks ornate. Try making all the edge detail come together in a flat smashy end.
