It took me a lot of time to come up with the right image for this one, because if you have seen any of my logos on this board, I really don't like angry logos.

The real life team is blue and silver (I darkened the blue), but there is probably a better color scheme for this. Not sure if it is better with the block color or with the little gradient on the lion, or with the "window" left open or closed.
