My first thoughts are that it is really simple and nothing much to it on a design perspective. The only thing that looks like its had some attention is the navigation. I then thought, did it load up correctly? I figured out it did.

Here's some points to consider;

1. Use some different fonts. You can use any type available now using various methods.

2. Add some structure to the design itself. Bring things out more, make it look less flat.
