looks nice - i would change not only the header but also the text color on the sidebar to something darker so it will be easier to read it on the orange background
Points: Agree with others. Header needs to be representative of the site's content. Font color of navigation is not easy on the eyes. Your navigation only lists Archives, which is not enough. You might want to add additional options, like pages, recent posts, popular posts etc.
At first i thought it was the usual duplicate content site. but it isn't. Make your site with more unique look and feel. Search for blogger templates. good luck.
I think some of the posts in your blog are aligned in proper manner but some are aligned not so good, check it out..
I think you should get your own domain name. A business site on a free domain doesn't seem professional to me.
yes, i really think too that you need you own domain. Al least an .info. The background color I don't like. personal opinion
nice blog but the color is not suiting for a business blog. you could probably shift to a more professional colors as well. add pictures as well
