Hello simplythai,
I agreee with the other members that one cannot tell what this site is about at first. You have to scroll almost to the bottom to find that out.

I suggest that you remove the scrolling title info.
1. It gets a little annoying
2. No good for your seo

Consider reworking your navigation. Either put it up top next to a picture / logo or on the left side of the page ...in the green area maybe?
Here is an example of a neat css menu-

Also try to keep your navigation consistant on every page. Some pages you loose the main menu and are forced to always you the back button.

On the home page it is probably no necessary to put 'Home Page' at the top of your page.
1. The user probably already knows this
2. It is a waste of valuable space

The font is large and you make your links even larger. I would suggest keeping everything the same size font.

You are on your way to having a great site. Post back when you make any changes :)
