I like that you made sure to refer to the design guidelines around colors and fonts. I like the color choices a lot.

The first design feels like it has too much empty space. Having some is good to prevent it from being too crowded, but that one might go a bit too far.

The second design is nice. I also like the idea of hovering for more information, but we'd want to make sure that 1. visitors understand they can/should hover and 2. that accessibility isn't compromised (e.g. people using screen readers should be able to navigate the site)

The footer would need some work as to the specific categories we put down there, but as a concept, I think it looks good.
