review my site which was changed by me last week site is given below http://www.herbalinfosite.com/ also give me advise on this category wizard http://www.herbalinfosite.com/article/article_Index.html
That google ad unit and the white space below the menu doesn't look right. I would consider replacing that with a link unit and if you want more ads then maybe a smaller horizontal ad would work right above the posts.
The site looks a bit disorganized I think the site would look much better if you got a more professional template.
The background image and that empty space between divs isn't as good as it looks. Color combination is a bit disorganize. Try creating a concept first for your site to achieve an effective design.
