Very good. Although I would like to add that the infinity stones do like like glowing stones and that the Orb and Tesseract are just shells for the actual gem. They all with the exception of the Aether look like the gem on Loki's scepter(which is 99% sure is the mind gem) and the gem inside the Orb which Ronan puts in his hammer. I also believe that the cube is the shell to the actual space gem inside, just like the other infinity gems.
