Background

I started with larger silhouettes of the mascot on a light background, but it didn't seem to sit right.

Used a darker blue that was lifted from the mascots colour scheme, but I think the silhouettes are still to big.

Dark gray background, same as the text, without the mascots.

Mascots at 5% opacity, tilted and set against the same gray background. This should keep attention on the middle of the page and it less of a distraction.
