webmasters - I seriously need your reviews for my website

Please review this site: www.dhtmlonline.com.
It is meant to be a web designer's site.  This site runs well on most browsers. At least i tested with Internet explorer, Netscape, Firefox and Opera.
I need your reviews, corrections where needed. Some people said since it is a Nigerian site, that i should use black pictures, some say it is just o.k like that.

Well, i need suggestions. Please do check it, it does not take long to load, it has no flash or java applet, and few images,
