There are some point i would change:

-The Background is Too Enoiing to me.
-The Nav. Has a To Big font. And maybe use Verdana or something.
-At the right part you used a bad font. You should use a cleaner font there too.
-Add more detailes to it.

(I just mention everything to help you, so don't get it like i totally hate it )

Good luck with Making it better
