The header looks really nice and professional! I would really like to see some more resources on your website. Infact I could partner with you and have some long term deals with you as I have many resources myself, that I would like to sell!
just an idea here but try a different shade for your background. maybe a light tan or greyish-white.. just something to lose the bright white.
It is a bit crowded. Please get better adsense placement. Those two 350x200 ads side by side are not looking good. Try to spread out the text in the entire site width instead of 800x600.
Very well structured site and Nice design..lol But the drop down color doesn't match the menu bar..IMO.. It would be better if you change the color of dropdown menu into blue BG and white(or any bright color) font.
