I appreciate any comments to help me improve this website.

Hi! this site it's helpful for me! ( my native language is Spanish!) In my opinion: Try to change the background. It's look very old fashion, enhace the colors, but don't abuse.
There's a search optimization good job, Title relevancy to page content is excellent (100%), Description relevancy to page content is good (94%,) but Keyword relevancy to page content is terrible! 0nly 14%. Try to improve this.
No navigations problems.
Good Luck!
